21.3
This section describes the memory map and registers for the Flash module. Read data from unimplemented
memory space in the Flash module is undefined. Write access to unimplemented or reserved memory space
in the Flash module will be ignored by the Flash module.

21.3.1
The S12 architecture places the P-Flash memory between global addresses 0x3_C000 and 0x3_FFFF as

Memory Map and Registers
Module Memory Map
Writing to the Flash registers while a Flash command is executing (that is
indicated when the value of flag CCIF reads as ’0’) is not allowed. If such
action is attempted the write operation will not change the register value.
Writing to the Flash registers is allowed when the Flash is not busy
executing commands (CCIF = 1) and during initialization right after reset,
despite the value of flag CCIF in that case (refer to
complete description of the reset sequence).
