MEMORY AND REGISTERS
The MC68HC05BD3/MC68HC705BD3/MC68HC05BD5 has a 16K-byte memory map consisting
of registers, user ROM/EPROM user RAM, self-check/bootstrapROM, and I/O as shown in
Figure 3-1.
3.1
Registers
All the I/O, control and status registers of the MC68HC05BD3 are contained within the first 48-byte
block of the memory map (address $0000 to $002F).
3.2
RAM (MC68HC05BD3)
The user RAM consists of 128 bytes of memory, from $0080 to $00FF. This is shared with a 64
byte stack area. The stack begins at $00FF and counts down to $00C0.
3.3
RAM (MC68HC705BD3/MC68HC05BD5)
The user RAM consists of 256 bytes of memory, from $0080 to $017F. This is shared with a 64
byte stack area. The stack begins at $00FF and counts down to $00C0.
Note:
Using the stack area for data storage or temporary work locations requires care to
prevent the data from being overwritten due to stacking from an interrupt or subroutine
call.
