10.9.1
TPU operation can be disabled or enabled using the module stop control register. The initial
setting is for TPU operation to be halted. Register access is enabled by clearing module stop
mode. For details, see section 22, Power-Down Modes.
10.9.2
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 TPU 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 10.44 shows the input clock
conditions in phase counting mode.
