µPD64A, 65
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 specified by the control register P13 and the register pair R10-R00 are
transferred to timer register T (t9 to t0).
The program memory, which consists of 10 bits, is placed in the following state after the transfer to the
register.
Program memory
Timer
T
t1
t9 t8 t7 t6
t0
t5 t4 t3 t2
→
t9 t8 t7 t6
t5 t4 t3 t2
t1 t0
@R0
T1
T0
The higher 3 bits of the program memory address are specified by the control register (P13).
Caution When setting a timer value in the program memory, be sure to use the DT quasi
directive.

HALT #data4
<1> Instruction code: 0 0 0 1 0 1 0 0 0 1
<2> Cycle count:
0 0 0 0 0 0 d3 d2 d1 d0
1
<3> Function:
Standby mode
Places the CPU in standby mode.
The condition to cancel the standby mode (HALT/STOP mode) is specified by 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 matches the bits that have been set, status flag F is set (1).
If none of them match, status flag F is cleared (0).
