a, I
Move immediate data into ACC.
Example: mov a, 0x0f;
Result: a ← 0fh;
Affected flags: 『N』Z 『N』C 『N』AC 『N』OV
M, a
a, M
Move data from ACC into memory
Example: mov
MEM, a;
Result: MEM ← a
Affected flags: 『N』Z 『N』C 『N』AC 『N』OV
Move data from memory into ACC
Example: mov
a, MEM ;
Result: a ← MEM; Flag Z is set when MEM is zero.
Affected flags: 『Y』Z 『N』C 『N』AC 『N』OV
a, IO
Move data from IO into ACC
Example: mov
a, pa ;
Result: a ← pa; Flag Z is set when pa is zero.
Affected flags: 『Y』Z 『N』C 『N』AC 『N』OV
IO, a
Move data from ACC into IO
Example: mov
Result: pb ← a
pb, a;
Affected flags: 『N』Z 『N』C 『N』AC 『N』OV
Move 16-bit counting values in Timer16 to memory in word.
Example: ldt16 word;
ldt16 word
Result:
word ← 16-bit timer
Affected flags: 『N』Z 『N』C 『N』AC 『N』OV
Application Example:
------------------------------------------------------------------------------------------------------------------------
word

stt16
…
lb@ T16val ;
hb@ T16val ;
T16val ;
// clear T16val (LSB)
// clear T16val (MSB)
// initial T16 with 0
set1
…
t16m.5 ;
// enable Timer16
set0
ldt16
….
t16m.5 ;
T16val ;
// disable Timer 16
// save the T16 counting value to T16val
