<2> Cycle count:

<3> Function:

(T)

← data10

The immediate data is transferred to the timer register T (t9 to t0).

Remark The timer time is set as follows.

(a)

µPD67, 68, and 69

(Set value + 1)

× 64/fX

(b)

µPD67A and 68A

(Set value + 1)

× 64/fX – 4/fX

MOV T, @R0

<1> Instruction code:

0 01111111 1

<2> Cycle count:

<3> Function:

(T)

← ((P13), (R0))

Transfers the program memory contents to the timer register T (t9 to t0) specified by the control register

P13 and the register pair R10 to R00.

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

@R0

→

Program memory

Timer

The higher 2 to 4 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.
