ldtabl

index

Load low byte data in OTP to ACC by using index as OTP address. It needs 2T to execute this

instruction.

Example:

ldtabl

index;

Result:

a ← {bit7~0 of OTP [index]};

Affected flags: 『N』Z

『N』C

『N』AC

『N』OV

Application Example:

------------------------------------------------------------------------------------------------------------------------

word

ROMptr ;

// declare a pointer of ROM in RAM

...

mov

a, la@TableA ; // assign pointer to ROM TableA (LSB)

mov

lb@ROMptr, a ; // save pointer to RAM (LSB)

mov

a, ha@TableA ; // assign pointer to ROM TableA (MSB)

mov

hb@ROMptr, a ; // save pointer to RAM (MSB)

...

ldtabl

ROMptr ;

// load TableA LSB to ACC (ACC=0x34)

...

TableA :

0x0234, 0x0042, 0x0024, 0x0018 ;

ldt16

word

Move 16-bit counting values in Timer16 to memory in word.

Example:

ldt16

word;

Result:

word

← 16-bit timer

Affected flags: 『N』Z

『N』C

『N』AC

『N』OV

Application Example:

------------------------------------------------------------------------------------------------------------------------

word

T16val ;

// declare a RAM word

...

clear

lb@ T16val ;

// clear T16val (LSB)

clear

hb@ T16val ;

// clear T16val (MSB)

stt16

T16val ;

// initial T16 with 0

...

set1

t16m.5 ;

// enable Timer16

...

set0

t16m.5 ;

// disable Timer16

ldt16

T16val ;

// save the T16 counting value to T16val

...

------------------------------------------------------------------------------------------------------------------------

stt16

word

Store 16-bit data from memory in word to Timer16.

Example:

stt16

word;

Result:

16-

bit timer ←word

Affected flags: 『N』Z
