[bit3:2] IRS[1:0]: Interrupt type select bit
These bits select the interrupt source type for the 16-bit PPG timer.
bit3:2
Writing "00"
Writing "01"
Writing "10"
Writing "11"
[bit1] POEN: Output enable bit
This bit enables or disables the 16-bit PPG timer output pin output.
bit1
Writing "0"
Writing "1"
[bit0] OSEL: Output inversion bit
This bit selects the polarity of the 16-bit PPG timer output pin.
When "0" is written to this bit, the PPG output goes to "H" when "L" is output in the internal start and the
16-bit downcounter value matches the duty setting register value, and goes to "L" when a downcounter
borrow occurs (normal polarity).
When "1" is written to this bit, the 16-bit PPG timer output is inverted (inverted polarity).
bit0
Writing "0"
Writing "1"
MN702-00009-2v0-E
Trigger by input, software trigger, or retrigger
Counter borrow
Rising edge of 16-bit PPG timer output in normal polarity, or falling edge of 16-bit PPG timer
output in inverted polarity
Counter borrow, rising edge of 16-bit PPG timer output in normal polarity, or falling edge of 16-
bit PPG timer output in inverted polarity
The 16-bit PPG timer output pin functions as a general-purpose I/O port.
The 16-bit PPG timer output pin functions as an output pin for the 16-bit PPG timer.
