DAL

ADDR3, r

IF DAL bit

= 0 then

load program in page

0 to DATA register

(Note)

IF DAL bit

= 1 then

load program

memory referring to

DAL address register

to DATA register

(Note)

DATA

ADDR3 (6 bits)

At P

= “0” H, the

condition is CPU

waiting

(Soft wait mode)

WAIT

At P

= “1” H, expect

for clock generator,

all function is waiting

(Hard wait mode)

Wait at condition P

Note: The lower four bits among the ten-bit address of the program memory specified with the DAL instruction (DAL

ADDR3 and r) are addressed indirectly with the contents of the general register.

Note: The execution period for the DAL instruction is two machine cycles

Note: DAL bit and DAL address register (DA) are arranged on I/O map.

(

→ Refer to the register port item)

Note: When “1” is set to DAL bit and DAL instruction is executed, all the operand part becomes invalid and reference

address is used for DAL address register (DA). In this case, assign 0, 0 as dummy data for the operand.
