µPD62A
MOV T, @R0
<1> Instruction code: 0 0 1 1 1 1 1 1 1 1
<2> Cycle count:
1
<3> Function:
(T) ← ((P13), (R0))
The program memory contents are transferred to the timer register T (t9 to t0) specified with the control
register P13 and the register pair R10-R00.
The program memory, which consists of 10 bits, is placed in the following state after being transferred
to the register.
Program memory
Timer

T0
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 0 0 1 0 1 0 0 0 1
: 0 0 0 0 0 0 d3 d2 d1 d0
<2> Cycle count:
1
<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 0 0 1 1 0 R3 R2 R1R0
<2> Cycle count:
1
<3> Function:
If statuses match F ← 1
else F ← 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).
