CHAPTER 16 8-/16-BIT PPG TIMER
■ Operation Modes of 8-/16-bit PPG Timer
●
8-bit PPG output 2-channel independent operation mode
The 8-bit PPG output 2-channel independent operation mode causes the 2-channel modules (PPGC and
PPGD) to operate as each independent 8-bit PPG timer.
Table 16.1-1 shows the interval times in the 8-bit PPG output 2-channel independent operation mode.
●
16-bit PPG output operation mode
The 16-bit PPG output operation mode concatenates the 2-channel modules (PPGC and PPGD) to operate
as a 16-bit 1-channel PPG timer.
Table 16.1-2 shows the interval times in this mode.
