Detailed description

â Transfers the contents of the high-order 2 bits of timer 1 to register W5, and transfers the contents of

the low-order 8 bits of timer 1 to registers A and B.

â When stopping (W10=0), transfers the contents of register W5 to the contents of the high-order 2 bits of

timer 1 and of the timer 1 reload register, and transfers the contents of registers A and B to the contents

of the low-order 8 bits of timer 1 and of the timer 1 reload register.

When operating (W10=1), transfers the contents of register W5 to the contents of the high-order 2 bits

of the timer 1 reload register, and transfers the contents of registers A and B to the contents of the low-

order 8 bits of the timer 1 reload register.

â Transfers the contents of timer 2 to registers A and B.

â Transfers the contents of registers A and B to timer 2 and timer 2 reload register.

â Transfers the contents of registers A and B to timer 2 reload register.

â Transfers the contents of timer 3 to registers A and B.

â Transfers the contents of registers A and B to timer 3 and timer 3 reload register R3L.

â Transfers the contents of registers A and B to timer 3 reload register R3H.
