MEMORY AND REGISTERS
The MC68HC05BS8/
MC68HC705BS8 has a 16K-byte memory map consisting of I/O registers,
user ROM/
EPROM, user RAM, EEPROM, self-check/bootstrap ROM as shown in Figure 4-1.
4.1
Registers
All the I/O, control and status registers of the MC68HC05BS8 are located within the rst 64-byte
block of the memory map (address $0000 to $003F).
4.2
RAM
The user RAM consists of 256 bytes of memory, from $0040 to $013F. 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.
4.3
ROM (MC68HC05BS8)
The user ROM consists of 10K-bytes of memory, from $1800 to $3FDF.
4.4
EPROM (MC68HC705BS8)
The user EPROM consists of 10K-bytes of memory, from $1800 to $3FDF.
