I/O AND CONTROL REGISTERS
The I/O and Control Registers reside in locations $0000-$001F. The overall orga-
nization of these registers is shown in Figure 2-2. The bit assignments for each
register are shown in Figure 2-3 and Figure 2-4. Reading from unimplemented
bits will return unknown states, and writing to unimplemented bits will be ignored.

2.3
RAM
The User RAM consists of 64 bytes (including the stack), located from $00C0 to
$00FF. The stack begins at address $00FF and proceeds down to $00C0. Using
the stack area for data storage or temporary work locations requires care to pre-
vent it from being overwritten due to stacking from an interrupt or subroutine call.
2.4
ROM
There are a total of 1240 bytes of user ROM on-chip. This includes 1232 bytes of
user ROM from locations $0300 to $07CF for user program storage and 8 bytes
for user vectors from locations $07F8 to $07FF. There are a total of 40 bytes of
Internal Test ROM on chip at locations $07D0 to $07EF and from $07F0 to $07F7.
