19. Multi-Function Timer Pulse Unit 3 (MTU3c)

(4) Operation When Error Occurs in Normal Mode and Operation is Restarted in Phase Counting

Mode

shows a case in which an error occurs in normal mode and operation is restarted in phase counting mode

after re-setting.

Figure 19.146

Error Occurrence in Normal Mode, Recovery in Phase Counting Mode

(1) to (10) are the same as in

(11) Set the phase counting mode.
(12) Initialize the pins with the TIOR register.
(13) Set MTU output using the MPC and port mode registers (PMR) corresponding to the I/O ports.
(14) Restart operation by setting the TSTRA register.

Note:

The phase counting mode can only be selected for MTU1 and MTU2, and therefore the TOERA register setting is
not necessary.
