Memory
2.5 Random-Access Memory (RAM)
2.6 Read-Only Memory (ROM)
General Release Specification
NOTE:
The user RAM consists of 128 bytes (including the stack) at locations
$0080–$00FF. The stack begins at address $00FF. The stack pointer
can access 64 bytes of RAM from $00FF to $00C0.
Using the stack area for data storage or temporary work locations
requires care to prevent it from being overwritten due to stacking from an
interrupt or subroutine call.
There are 2256 bytes of user ROM at locations $0100–$08FF and
$1F00–$1FCF, with 48 bytes in user page zero locations $0020–$004F,
and 16 additional bytes for user vectors at locations $1FF0–$1FFF. The
test ROM and test ROM vectors are at locations $1FD0–$1FEF.
