INIT — RAM and I/O Mapping Register
4.2.2.2 INIT Register
RAM[3:0] — RAM Map Position
REG[3:0] — 64-Byte Register Block Position
TECHNICAL DATA
RESET:
The internal registers used to control the operation of the MCU can be relocated on 4K
boundaries within the memory space with the use of INIT. This 8-bit special-purpose
register can change the default locations of the RAM and control registers within the
MCU memory map. It can be written to only once within the first 64 E-clock cycles after
a reset, and then it becomes a read-only register.
These four bits, which specify the upper hexadecimal digit of the RAM address, control
position of RAM in the memory map. RAM can be positioned at the beginning of any
4K page in the memory map. It is initialized to address $0040 out of reset. Refer to
Table 4-3.
These four bits specify the upper hexadecimal digit of the address for the 64-byte block
of internal registers. The register block, positioned at the beginning of any 4K page in
the memory map, is initialized to address $0000 out of reset. Refer to Table 4-4.
