Usage Notes

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 module stop

state. For details, refer to section 23, 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.
