MEMORY AND REGISTERS
The MC68HC05F4 has a 16K byte memory map consisting of registers (for I/O, control and
status), user RAM, user ROM, EEPROM, bootloader ROM and reset and interrupt vectors as
shown in Figure 3-1.
3.1
Registers
All the I/O, control and status registers of the MC68HC05F4 are contained within the rst 64 byte
block of the memory map, as detailed in Table 3-1.
3.2
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 may extend 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.
3.3
ROM
The user ROM occupies 3840 bytes of memory, from $3000 to $3EFF. In addition, there are 16
bytes of user vectors, from $3FF0 to $3FFF.
