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 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, ensure to use the DT directive.
Places the CPU in standby mode.
The condition for having the standby mode (HALT/STOP mode) canceled is specified with the immediate
data.
Compares the S
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).
