Boot Configuration Vector
The encoding of the boot configuration vector is described in Table 3, and the vector input is illustrated in Figure 4. The value of the boot configura-
tion vector read in by the RC32434 during a cold reset may be determined by reading the Boot Configuration Vector (BCV) Register.
Signal
Name/Description
MADDR[3:0]
CPU Pipeline Clock Multiplier. This field specifies the value by which the PLL multi-
plies the master clock input (CLK) to obtain the processor clock frequency (PCLK). For
master clock input frequency constraints, refer to Table 3.2 in the RC32434 User Man-
ual.
0x0 - PLL Bypass
0x1 - Multiply by 3
0x2 - Multiply by 4
0x3 - Multiply by 5 - Reserved
0x4 - Multiply by 5
0x5 - Multiply by 6 - Reserved
0x6 - Multiply by 6
0x7 - Multiply by 8
0x8 - Multiply by 10
0x9 through 0xF - Reserved
MADDR[5:4]
External Clock Divider. This field specifies the value by which the IPBus clock
(ICLK), which is always 1/2 PCLK, is divided in order to generate the external clock
output on the EXTCLK pin.
0x0 - Divide by 1
0x1 - Divide by 2
0x2 - Divide by 4
0x3 - reserved
MADDR[6]
Endian. This bit specifies the endianness.
0x0 - little endian
0x1 - big endian
MADDR[7]
Reset Mode. This bit specifies the length of time the RSTN signal is driven.
0x0 - Normal reset: RSTN driven for minimum of 4000 clock cycles. If the internal boot
configuration vector is selected, the expiration of an 18-bit counter operating at the
master clock input (CLK) frequency is used as the PLL stabilization delay.
0x1 - Reserved
MADDR[10:8]
PCI Mode. This bit controls the operating mode of the PCI bus interface. The initial
value of the EN bit in the PCIC register is determined by the PCI mode.
0x0 - Disabled (EN initial value is zero)
0x1 - PCI satellite mode with PCI target not ready (EN initial value is one)
0x2 - PCI satellite mode with suspended CPU execution (EN initial value is one)
0x3 - PCI host mode with external arbiter (EN initial value is zero)
0x4 - PCI host mode with internal arbiter using fixed priority arbitration algorithm
(EN initial value is zero)
0x5 - PCI host mode with internal arbiter using round robin arbitration algorithm
(EN initial value is zero)
0x6 - reserved
0x7 - reserved
