Result:

a ← 0fh;

Affected flags: 『N』Z

『N』C

『N』AC

『N』OV

mov

M, a

Move data from ACC into memory

Example:

mov

MEM, a;

Result:

MEM ← a

Affected flags: 『N』Z

『N』C

『N』AC

『N』OV

mov

a, M

Move data from memory into ACC

Example:

mov

a, MEM ;

Result:

a ← MEM; Flag Z is set when MEM is zero.

『N』OV

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 Timer 16

ldt16

T16val ;

// save the T16 counting value to T16val

….
