CHAPTER 16 8-/16-BIT PPG TIMER
●
8+8-bit PPG output operation mode
The 8 + 8-bit PPG output operation mode causes the PPGC of the 2-channel modules to operate as an 8-bit
prescaler and the underflow output of the PPGC to operate as the count clock of the PPGD.
Table 16.1-3 shows the interval times in this mode.

HCLK: Oscillation clock
φ : Machine clock
The parenthesized values are provided when the oscillation clock operates at 4 MHz and the machine clock operates
at 24 MHz.
