12.3.2.1 ROM Array Addressing
12.4 ROM Module Control and Configuration Registers
12.4.1 Module Configuration Register (ROMMCR)
MC68F375
REFERENCE MANUAL
The array may be specified to reside in supervisor space to restrict access to supervi-
sor only, or it may be specified to exist in unrestricted space to allow access by both
user and supervisor programs. The array may also be configured to respond to pro-
gram space accesses only or to both data and program space accesses.
The BIU of the ROM module compares internal address [23:13] of the IMB3 with ROM-
BAH, ROMBAL[23:13]. If they match, the remaining address bits and ISIZ[1:0] are
used to access the ROM location in the array. Function codes are also checked for the
correct access rights. If the array is specified to exist in supervisor space, user
accesses will be ignored allowing an external device to respond to the address. If the
array is specified to exist in unrestricted space, it will respond to both user and super-
visor accesses. If the array is specified to exist in program space only, data space
accesses to the array will be ignored allowing implementation of separate data and
program space address maps."
This section describes the ROM control and configuration registers. Each register field
is described in detail with regard to operation. The ROM module register map is shown
in
The ROM module configuration register is used to control the operation of the ROM
array and provide status information. It also provides the production tester and the cus-
tomer with configuration information.
