CHAPTER 8 16-BIT 2-PHASE ENCODER INPUT UP/DOWN COUNTER/GENERAL-PURPOSE TIMER (TIMER ENC1n)
(b) Mode 2 (PRM1n.PRM1n2 bit = 1, PRM1n.PRM1n1 bit = 0, PRM1n.PRM1n0 bit = 1)
(c) Mode 3 (PRM1n.PRM1n2 = 1, PRM1n.PRM1n1 = 1, PRM1n.PRM1n0 = 0)
Figure 8-6. Mode 2 (When Rising Edge Is Specified as Valid Edge of TIUD1n, TCUD1n Pins)
The count conditions in mode 2 are as follows.
• TMENC1n count up upon detection of valid edge of TIUD1n pin
• TMENC1n count down upon detection of valid edge of TCUD1n pin
Caution If the count clock is simultaneously input to the TIUD1n pin and the TCUD1n pin, a count
In mode 3, when two signals 90 degrees out of phase are input to the TIUD1n and TCUD1n pins, the level
of the TCUD1n pin is sampled at the input of the valid edge of the TIUD1n pin (see Figure 8-7).
If the TCUD1n pin level sampled at the valid edge input to the TIUD1n pin is low, TMENC1n counts down
when the valid edge is input to the TIUD1n pin.
If the TCUD1n pin level sampled at the valid edge input to the TIUD1n pin is high, TMENC1n counts up
when the valid edge is input to the TIUD1n pin.
