MOV T, @R0
<1> Instruction code
<2> Cycle count
<3> Function
Transfers the program memory contents to the timer register T (t
9
to t
0
) specified with the control register
P13 and the register pair R
10
-R
00
.
The program memory, which consists of 10 bits, is placed in the following state after the transfer to the
register.
