The program counter is restored to its previous value
from the stack at the end of subroutine or interrupt rou-
tine, which is signaled by return instruction (RET or
RETI). After a chip resets, SP will point to the top of the
stack.
The interrupt request flag will be recorded but the ac-
knowledgment will be inhibited when the stack is full and
a non-masked interrupt takes place. After the stack
pointer is decremented (by RET or RETI), the interrupt
request will be serviced. This feature prevents stack
overflow and allows programmers to use the structure
more easily. In a similar case, if the stack is full and a
CALL is subsequently executed, stack overflow oc-
curs and the first entry is lost.
Data Memory
RAM
The data memory is designed with 208 8 bits. The data
memory is further divided into two functional groups,
namely, special function registers (00H~2AH) and gen-
eral purpose user data memory (30H~FFH). Although
mostofthemcanbereadorbewrittento,someareread
only.
The special function registers include an indirect ad-
dressing register (R0:00H), memory pointer register
(MP0:01H), accumulator (ACC:05H), program counter
lower-order byte register (PCL:06H), table pointer
(TBLP:07H), table higher-order byte register
(TBLH:08H), status register (STATUS:0AH), interrupt
control register 0 (INTC:0BH), Timer/Event Counter 0
(TMR0H:0CH,TMR0L:0DH), Timer/Event Counter 0
control register (TMR0C:0EH), Timer/Event Counter 1
(TMR1H:0FH, TMR1L:10H), Timer/Event Counter 1
control register (TMR1C:11H), I/O registers
(PA:12H,PB:14H), I/O control registers (PAC:13H,
PBC:15H), voice ROM address latch0[17:0]
(LATCH0H:18H, LATCH0M:19H, LATCH0L:1AH),
voice ROM address latch1[17:0] (LATCH1H:1BH,
LATCH1M:1CH, LATCH1L:1DH), interrupt control reg-
ister 1 (INTCH:1EH), table pointer higher-order byte
register (TBHP:1FH), Timer Counter 3 (TMR3L:24H),
Timer Counter 3 control register (TMR3C:25H), voice
control register (VOICEC:26H), DAC output
(DAH:27H,DAL:28H), volume control register
(VOL:29H), voice ROM latch data register
(LATCHD:2AH).
The general purpose data memory, addressed from
30H~FFH, is used for data and control information un-
der instruction commands.
The areas in the RAM can directly handle the arithmetic,
logic, increment, decrement, and rotate operations. Ex-
cept some dedicated bits, each bit in the RAM can be
set and reset by SET [m].i and CLR [m].i . They are
also indirectly accessible through the memory pointer
register 0 (MP0:01H) or the Memory Pointer register 1
(MP1:03H).
