The maximum CCLK frequency not only depends on the part's
maximum instruction rate (see Page 88 ). This frequency also
depends on the applied V DDINT voltage. See Table 12 and
depends on the chip package and the applied V DDINT , V DDEXT ,
and V DDMEM voltages (see Table 14 and Table 17 ).
BOOTING MODES
The processor has several mechanisms (listed in Table 8 ) for
automatically loading internal and external memory after a
reset. The boot mode is defined by four BMODE input pins
dedicated to this purpose. There are two categories of boot
modes. In master boot modes the processor actively loads data
from parallel or serial memories. In slave boot modes the pro-
cessor receives data from external host devices.
The boot modes listed in Table 8 provide a number of mecha-
nisms for automatically loading the processor’s internal and
external memories after a reset. By default, all boot modes use
the slowest meaningful configuration settings. Default settings
can be altered via the initialization code feature at boot time or
by proper OTP programming at pre-boot time. The BMODE
pins of the reset configuration register, sampled during power-
on resets and software-initiated resets, implement the modes
Table 8. Booting Modes
kernel performs an 8- or 16-bit boot or starts program exe-
cution at the address provided by the header. By default, all
configuration settings are set for the slowest device possible
(3-cycle hold time, 15-cycle R/W access times, 4-cycle
setup).
The ARDY is not enabled by default, but it can be enabled
through OTP programming. Similarly, all interface behav-
ior and timings can be customized through OTP
programming. This includes activation of burst-mode or
page-mode operation. In this mode, all asynchronous
interface signals are enabled at the port muxing level.
? Boot from 16-bit asynchronous FIFO (BMODE = 0x2) —
In this mode, the boot kernel starts booting from address
0x2030 0000. Every 16-bit word that the boot kernel has to
read from the FIFO must be requested by placing a low
pulse on the DMAR1 pin.
? Boot from serial SPI memory, EEPROM or flash
(BMODE = 0x3) — 8-, 16-, 24-, or 32-bit addressable
devices are supported. The processor uses the PG1 GPIO
pin to select a single SPI EEPROM/flash device and sub-
mits a read command and successive address bytes (0x00)
until a valid 8-, 16-, 24-, or 32-bit addressable device is
detected. Pull-up resistors are required on the SPISEL1 and
MISO pins. By default, a value of 0x85 is written to the
SPI_BAUD register.

? Boot from SPI host device (BMODE = 0x4) — The proces-
sor operates in SPI slave mode and is configured to receive
the bytes of the LDR file from an SPI host (master) agent.
The HWAIT signal must be interrogated by the host before
every transmitted byte. A pull-up resistor is required on the
SPISS input. A pull-down on the serial clock (SCK) may
improve signal quality and booting robustness.
? Boot from serial TWI memory, EEPROM/flash
(BMODE = 0x5) — The processor operates in master mode
and selects the TWI slave connected to the TWI with the
unique ID 0xA0.
The processor submits successive read commands to the
memory device starting at internal address 0x0000 and
begins clocking data into the processor. The TWI memory
device should comply with the Philips I 2 C ? Bus Specifica-
tion version 2.1 and should be able to auto-increment its
internal address counter such that the contents of the
memory device can be read sequentially. By default, a
PRESCALE value of 0xA and a TWI_CLKDIV value of
0x0811 are used. Unless altered by OTP settings, an I 2 C
memory that takes two address bytes is assumed. The
development tools ensure that data booted to memories
that cannot be accessed by the Blackfin core is written to an
? Idle/no boot mode (BMODE = 0x0) — In this mode, the
processor goes into idle. The idle boot mode helps recover
from illegal operating modes, such as when the OTP mem-
ory has been misconfigured.
? Boot from 8-bit or 16-bit external flash memory
(BMODE = 0x1) — In this mode, the boot kernel loads the
first block header from address 0x2000 0000, and (depend-
ing on instructions contained in the header) the boot
intermediate storage location and then copied to the final
destination via memory DMA.
? Boot from TWI host (BMODE = 0x6) — The TWI host
selects the slave with the unique ID 0x5F.
The processor replies with an acknowledgement and the
host then downloads the boot stream. The TWI host agent
should comply with the Philips I 2 C Bus Specification
