2.4 Random-Access Memory (RAM)
The following table shows the RAM size and address range:
Device
MC68HC908AP64
MC68HC908AP32
MC68HC908AP16
MC68HC908AP8
RAM Size (Bytes)
2,048
1,024
Memory Address Range
$0060–$085F
$0060–$045F
The location of the stack RAM is programmable. The 16-bit stack pointer allows the stack to be anywhere
in the 64k-byte memory space.
