MOV T, @R0

<1> Instruction code:

0 01111111 1

<2> Cycle count:

<3> Function:

(T)

← ((P13), (R0))

The program memory contents are transferred to the timer register T (t9 to t0) specified with the control

The program memory, which consists of 10 bits, is placed in the following state after being transferred

to the register.

@R0

→

Program memory

Timer

The high-order 2 bits of the program memory address are specified with the control register (P13).

Caution When setting a timer value in the program memory, be sure to use the DT directive.

HALT #data4

<1> Instruction code:

0 00101000 1

0 00000 d3 d2 d1 d0

<2> Cycle count:

<3> Function:

Standby mode

Places the CPU in standby mode.

The condition for having the standby mode (HALT/STOP mode) canceled is specified with the immediate

data.

STTS R0n

<1> Instruction code:

0 00110 R3 R2 R1 R0

<2> Cycle count:

<3> Function:

If statuses match

← 1

else

← 0 n = 0 to F

The S0, S1, KI/O, KI, and TIMER statuses are compared with the register R0n contents. If at least one

of the statuses coincides with the bits that have been set, the status flag F is set (to 1).

If none of them coincide, the status flag F is cleared (to 0).
