<3> Function:
(A) ← (Tn) n = 0, 1
CY ← 0
The timer Tn contents are transferred to the accumulator. T1 corresponds to (t9, t8, t7, t6); T0 corresponds
to (t5, t4, t3, t2).

<1> Instruction code: 0 0 1 0 0/1 1 1 1 1 1
<2> Cycle count:
1
<3> Function:
(Tn) ← (A) n = 0, 1
The accumulator contents are transferred to timer register Tn. T1 corresponds to (t9, t8, t7, t6); T0
corresponds to (t5, t4, t3, t2). After executing this instruction, if data is transferred to T1, t1 becomes
0; if data is transferred to T0, t0 becomes 0.
MOV T, #data10

<3> Function:
(T) ← data10
The immediate data is transferred to timer register T (t9-t0).
Remark The timer time is set with (set value + 1) × 64/fX (or 128/fX).
