(1) Timer control registers
q Timer control register W1
Register W1 controls the count source of timer 1, the
frequency dividing ratio and count operation of prescaler.
Set the contents of this register through register A with
the TW1A instruction. The TAW1 instruction can be used
to transfer the contents of register W1 to register A.
q Timer control register W2
Register W2 controls the count operation of timer 1 and
count operation and count source of timer 2. Set the
contents of this register through register A with the TW2A
instruction. The TAW2 instruction can be used to transfer
the contents of register W2 to register A.
q Timer control register W3
Register W3 controls the count operation and count source
of timer LC. Set the contents of this register through
register A with the TW3A instruction. The TAW3 instruction
can be used to transfer the contents of register W3 to
register A.
