16-bit 2-Phase Encoder Input Up/Down Counter/General Purpose Timer (TMENC10)
User’s Manual U16580EE3V1UD00
(d) Mode 4 (PRM102 to PRM100 bits = 111B)
In mode 4, when two signals out of phase are input to the TIUD1 and TCUD1 pins, up/down
operation is automatically judged and counting is performed according to the timing shown in
Figure 12-20
.
In mode 4, counting is executed at both the rising and falling edges of the two signals input to the
TIUD1 and TCUD1 pins. Therefore, TMENC10 counts four times per cycle of an input signal
(
×
4 count).
Figure 12-20:
Mode 4
Cautions: 1. When mode 4 is specified as the operation mode of TMENC10, the valid edge
specifications for pins TIUD1 and TCUD1 are not valid.
2. If the TIUD1 pin edge and TCUD1 pin edge are input simultaneously in mode 4,
TMENC10 continues the same count operation (up or down) it was performing
immediately before the input.
