PFS122
8bit MTP MCU with 12-bit R-Type ADC
stt16 word
Store 16-bit data from memory in word to Timer16.
Example: stt16 word;
Result:
16-bit timer ←word
Affected flags: 『N』Z 『N』C 『N』AC 『N』OV
Application Example:
------------------------------------------------------------------------------------------------------------------------
word
…
T16val ;
// declare a RAM word
mov
mov
mov
mov
stt16
…
a, 0x34 ;
lb@ T16val , a ; // move 0x34 to T16val (LSB)
a, 0x12 ;
hb@ T16val , a ; // move 0x12 to T16val (MSB)
T16val ;
// initial T16 with 0x1234
----------------------------------------------------------------------------------------------------------------------
Idxm a, index
Move data from specified memory to ACC by indirect method. It needs 2T to execute this
instruction.
Example: idxm a, index;
Result:
a ← [index], where index is declared by word.
Affected flags: 『N』Z 『N』C 『N』AC 『N』OV
Application Example:
------------------------------------------------------------------------------------------------------------------------
word
…
RAMIndex ;
// declare a RAM pointer
mov
mov
mov
mov
…
a, 0x5B ;
// assign pointer to an address (LSB)
// save pointer to RAM (LSB)
lb@RAMIndex, a ;
a, 0x00 ;
// assign 0x00 to an address (MSB), should be 0
// save pointer to RAM (MSB)
hb@RAMIndex, a ;
idxm
a, RAMIndex ;
// move memory data in address 0x5B to ACC
------------------------------------------------------------------------------------------------------------------------
Idxm index, a Move data from ACC to specified memory by indirect method. It needs 2T to execute this
instruction.
Example: idxm index, a;
Result:
[index] ← a; where index is declared by word.
Affected flags: 『N』Z 『N』C 『N』AC 『N』OV
Application Example:
------------------------------------------------------------------------------------------------------------------------
word
…
RAMIndex ;
// declare a RAM pointer
mov

hb@RAMIndex, a ; // save pointer to RAM (MSB)
mov
idxm
a, 0xA5 ;
RAMIndex, a ;
// mov 0xA5 to memory in address 0x5B
