CHAPTER 16 8-/16-BIT PPG TIMER

16.3.2

PPGD Operation Mode Control Register (PPGCD)

The PPGD operation mode control register provides the following settings about
operation of 8-/16-bit PPG timer D:
• Enabling or disabling operation of 8-/16-bit PPG timer D
• Switching between pin functions (enabling or disabling pulse output)
• Enabling or disabling underflow interrupt
• Setting underflow interrupt request flag
• Setting the operation mode of the 8-/16-bit PPG timer D and C
This section explains the PPGCD function only. The PPGCF has the same function as
the PPGCD, and the 8-/16-bit PPG timer F is set.
