1. This bit is available only on the MPC555 / MPC556.
When a soft reset event occurs, the MPC555 / MPC556 reconfigures the development
port. Refer to

SECTION 21 DEVELOPMENT SUPPORT
Debug port pins configuration. See
field definition. The default value is for these pins to function as development support pins.
Address type write-enable configuration. Refer to
ister
External bus division factor. This field defines the initial value of the external bus frequency.
Refer to
CLKOUT frequency is equal to that of the internal clock (divide by one).
Reserved
Peripheral mode enable. This bit determines whether the chip is in peripheral mode. Refer to
6.13.1.3 External Master Control Register (EMCR)
ripheral mode is not enabled.
Single chip select. Refer to
00 = Extended chip, 32 bits data
01 = Extended chip, 16 bits data
10 = Single chip and show cycles (address)
11 = Single chip
Exception table relocation enable. This field defines whether the exception table relocation
feature in the BBC is enabled or disabled. The default state is disabled. Refer to
BURST BUFFER
Flash Enable — This field determines whether the on-chip flash memory is enabled or dis-
abled out of reset. The default state is disabled, which means that by default, the boot is from
external memory.
0 = Flash disabled — boot is from external memory
1 = Flash enabled
Enable Compression — This bit enables the operation of the MPC555 / MPC556 with com-
pressed code. The default state is disabled. See
Exception Compression — This bit determines the operation of the MPC555 with exceptions.
If this bit is set, than the MPC555 assumes that ALL the exception routines are in compressed
code. The default indicates the exceptions are all non-compressed. See
This bit should not be high in the reset configuration word.
Reserved
Initial internal space base select. This field defines the initial value of the ISB field in the IMMR
register. Refer to
the internal memory map is mapped to start at address 0x0000 0000.
Dual mapping enable. This bit determines whether dual mapping of the flash EEPROM mod-
ule is enabled. Refer to
value is for dual mapping to be disabled.
0 = Dual mapping disabled
1 = Dual mapping enabled
for this field definition. The default value is for these pins to function as write-enable pins.
