14.1.2.1 Counter Reset by Two-Phase Pulse Signal Processing
3
0
The timer counter is reset to "0" by a Z-phase input when processing a two-phase pulse signal.
This function can be used in timer A3 event counter mode, two-phase pulse signal processing, free-
run type or multiply-by-4 processing. The Z-phase signal is applied to the INT2 pin.
When the TAZIE bit in the ONSF register is set to "1" (Z-phase input enabled), the timer counter can
be reset by a Z-phase input. To reset the timer counter by a Z-phase input, set the TA3 register to
"0000
Z-phase input is enabled when the edge of the signal applied to the INT2 pin is detected. The POL bit
in the INT2IC register can determine edge polarity. The Z-phase must have a pulse width of one timer
A3 count source cycle or more. Figure 14.10 shows two-phase pulses (A-phase and B-phase) and
the Z-phase.
Z-phase input resets the counter in the next count source following Z-phase input. Figure 14.11 shows
the counter reset timing.
Timer A3 interrupt request is generated twice when a timer A3 overflow or underflow, and a counter
reset by INT2 input occur at the same time. Do not use the timer A3 interrupt request when this
function is used.
