This section describes the pins of the multi-pulse generator.
■ Pins of Multi-pulse Generator
The multi-pulse generator uses OPT0 to OPT5, SNI0 to SNI2, DTTI and TI1.
● OPT0 to OPT5 pins
The OPT0 to OPT5 pins function as waveform output pins for the multi-pulse generator.
Regardless of the port direction register (DDR) value, enabling waveform output
(OPCLR:OPE[5:0] = 0b111111) automatically makes the OPT0 to OPT5 pins function as
waveform output pins for the multi-pulse generator.
● SNI0 to SNI2 pins
The SNI0 to SNI2 pins function as the position detect input pins for the multi-pulse generator.
Set the corresponding bits in the port direction register (DDR) to "0" to use the SNI0, SNI1 and
SNI2 pins as input ports.
● DTTI pin
The DTTI pin functions as the DTTI input pin for the multi-pulse generator.
Set the corresponding bit in the port direction register (DDR) to "0" to use the DTTI pin as an
input port.
● TI1 pin
The TI1 pin functions as the input pin of the 16-bit reload timer for the multi-pulse generator.
Set the corresponding bit in the port direction register (DDR) to "0" to use the TI1 pin as an
input port.
