Section 10 Multi-Function Timer Pulse Unit 2 (MTU2)
10.7
10.7.1
MTU2 operation can be disabled or enabled using the standby control register. The initial setting
is for MTU2 operation to be halted. Register access is enabled by clearing module standby mode.
For details, refer to section 24, Power-Down Modes.
10.7.2
The input clock pulse width must be at least 1.5 states in the case of single-edge detection, and at
least 2.5 states in the case of both-edge detection. The MTU2 will not operate properly at narrower
pulse widths.
In phase counting mode, the phase difference and overlap between the two input clocks must be at
least 1.5 states, and the pulse width must be at least 2.5 states. Figure 10.119 shows the input clock
conditions in phase counting mode.
