Section 10 16-Bit Timer Pulse Unit (TPU)

10.10.1 Module Stop State Setting
Operation of the TPU can be disabled or enabled using the module stop control register. The initial
setting is for operation of the TPU to be halted. Register access is enabled by clearing the module
stop state. For details, refer to section 20, Power-Down Modes.
10.10.2 Input Clock Restrictions
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 with a
narrower pulse width.
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 10.45 shows the input clock
conditions in phase counting mode.
