The immediate data is transferred to the timer register T (t
The immediate data is transferred to the modulo register M0 (t
The immediate data is transferred to the modulo register M1 (t
Transfers the program memory contents to the timer register T (t
P13 and the register pair R
The program memory, which consists of 10 bits, is placed in the following state after the transfer to the
register.
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
Remark The timer time is set as follows.
