11.4.5
11.4.6 Quadruple mode
TB0CIN0
TB0CIN1
Two-phase Pulse Input Count Mode (
In this mode, the counter is incremented or decremented by one depending on the state
transition of the two-phase clock that is input through TB0CIN0 and TB0CIN1 and has
phase difference. Interrupt is output in the ups and downs counter mode by the count
operation.
This is a quadruple mode that performs count-up/ down in every modes.
TMRB0C has the same two phase pulse mode as TMRB12. Here we give a detailed
description of TMRB0C.
