Figure 9. Frequency Modification Methods
All on-chip peripherals are clocked by the system clock (SCLK).
The system clock frequency is programmable by means of the
SSEL3–0 bits of the PLL_DIV register. The values programmed
into the SSEL fields define a divide ratio between the PLL output
(VCO) and the system clock. SCLK divider values are 1 through
15. Table 6 illustrates typical system clock ratios.

from address 0x2000 0000 with 16-bit packing. The boot
ROM is bypassed in this mode. All configuration settings
are set for the slowest device possible (3-cycle hold time;
15-cycle R/W access times; 4-cycle setup).
? Boot from 8-bit or 16-bit external flash memory – The flash
boot routine located in boot ROM memory space is set up
The maximum frequency of the system clock is f SCLK . The divi-
sor ratio must be chosen to limit the system clock frequency to
its maximum of f SCLK . The SSEL value can be changed dynami-
cally without any PLL lock latencies by writing the appropriate
values to the PLL divisor register (PLL_DIV). When the SSEL
value is changed, it affects all of the peripherals that derive their
clock signals from the SCLK signal.
The core clock (CCLK) frequency can also be dynamically
changed by means of the CSEL1–0 bits of the PLL_DIV register.
Supported CCLK divider ratios are 1, 2, 4, and 8, as shown in
fast core frequency modifications.
using asynchronous Memory Bank 0. All configuration set-
tings are set for the slowest device possible (3-cycle hold
time; 15-cycle R/W access times; 4-cycle setup).
? Boot from SPI serial EEPROM/flash (8-, 16-, or 24-bit
addressable, or Atmel AT45DB041, AT45DB081, or
AT45DB161) – The SPI uses the PF2 output pin to select a
single SPI EEPROM/flash device, submits a read command
and successive address bytes (0x00) until a valid 8-, 16-, or
24-bit addressable EEPROM/flash device is detected, and
begins clocking data into the processor at the beginning of
L1 instruction memory.
? Boot from SPI serial master – The Blackfin processor oper-
ates in SPI slave mode and is configured to receive the bytes
of the LDR file from an SPI host (master) agent. To hold off
the host device from transmitting while the boot ROM is
busy, the Blackfin processor asserts a GPIO pin, called host
wait (HWAIT), to signal the host device not to send any
