3 On-Chip Memory
The MC68HC11C0 has 256 bytes of RAM. A 1024-byte block of bootstrap ROM is present in single-
chip, bootstrap, and test modes. The following paragraphs describe the memory systems of this MCU.
3.1 Memory Map and Register Block
The INIT register control the location of the registers in the 64-Kbyte CPU address space. The 128-byte
register block originates at $0000 after reset and can be placed at any 1-Kbyte boundary by writing an
appropriate value to the INIT register. The INIT register can be written only in the first 64 cycles after
reset. If the register block and RAM are placed at the same 1-Kbyte boundary, the first 128 bytes of
RAM are inaccessible. This is due to an on-chip hardware priority scheme which eliminates conflicts
which could arise from multiple resources sharing address locations. Refer to the memory map dia-
gram.
Can be written only once in first 64 cycles in expanded and single-chip modes or at any time in other
modes.
REG[15:10] — Internal Register Map Position
These bits determine the upper six bits of the register block address. At reset registers are mapped to
$0000–$007F. Refer to the memory map diagram.
