15.1.2.1 Counter Reset by Two-Phase Pulse Signal Processing
0
G
Z-phase input resets the timer counter when processing a two-phase pulse signal.
This function can be used in timer A3 event counter mode, two-phase pulse signal processing, free-
running count operation 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), Z-phase input can
reset the timer counter. To reset the counter by a Z-phase input, set the TA3 register to "0000
beforehand.
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 15.10 shows two-phase pulses (A-phase and B-phase) and
the Z-phase.
Z-phase input resets the timer counter in the next count source following Z-phase input. Figure 15.11
shows the counter reset timing.
Timer A3 interrupt request is generated twice continuously 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.
