10.10 Usage Notes
10.10.1 Module Stop Mode Setting
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, refer to section 22, 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 at narrower
pulse widths.
In the H8S/2268 Group 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.
