A
This function resets the timer counter to “0” when the Z-phase (counter reset) is input during two-
phase pulse signal processing.
This function can only be used in timer A3 event counter mode, two-phase pulse signal processing,
free-run type, and multiply-by-4 processing. The Z phase is input to the INT2 pin.
When the Z-phase input enable bit (bit 5 at address 0342

timer A3 register (address 034D
The Z-phase is input when the INT2 input edge is detected. The edge polarity is selected by the INT2
polarity switch bit (bit 4 at address 009C
of the timer A3 count source. Figure 13.8 shows the relationship between the two-phase pulse (A
phase and B phase) and the Z phase.
The counter is reset at the count source following Z-phase input. Figure 13.9 shows the timing at
which the counter is reset to “0”.
