Multi-pulse Generator Pins
This section describes the pins of the Multi-pulse Generator and provides a pin block
diagram.
■ Pins of Multi-pulse Generator
Multi-pulse Generator uses P00/OPT0 to P05/OPT5, P43/SNI0 to P45/SNI2, P12/INT2/DTTI1 and P15/
INT5/TIN0.
●
P00/OPT0 to P05/OPT5 Pins
P00/OPT0 to P05/OPT5 pins can function either as a general-purpose I/O port (P00 to P05) or as waveform
output for Multi-pulse Generator.
Enabling waveform output bit (OPCLR: OPE5 to OPE0 = 111111
P05/OPT5 pin as an output pin, regardless of the port data direction register (DDR0: bit5 to bit0) value, and
sets the pin to function as the OPT5 to OPT0 pin.
●
P43/SNI0 to P45/SNI2 Pins
P43/SNI0 to P45/SNI2 pins can function either as a general-purpose I/O port (P43 to P45) or as the position
detect input for Multi-pulse Generator.
Set P43/SNI0 to P45/SNI2 pins as an input port in the data direction register (DDR4: bit5 to bit3 = 000
when using as SNI2 to SNI0 pins.
●
P12/INT2/DTTI1 Pin
P12/INT2/DTTI1 pin can function either as a general-purpose I/O port (P12) or external interrupt INT2, or
as the DTTI1 input for Multi-pulse Generator.
Set P12/INT2/DTTI1 pin as an input port in the data direction register (DDR1: bit1 = 0) when using as
DTTI1 pins.
●
P15/INT5/TIN0 Pin
P15/INT5/TIN0 pin can function either as a general-purpose I/O port (P15) external interrupt INT5, or as
the input of 16-bit Reload Timer 0 for Multi-pulse Generator.
Set P15/INT5/TIN0 pin as an input port in the data direction register (DDR1: bit5 = 0) when using as TIN0
pins.
