pp0: Push-Pull Output IO0 bit
Setting this bit to a ‘ 1 ’, with bit OE0 set to a ‘ 1 ’, will configure the IO0 (NTC) pin as a push-pull
digital output. If pp0 is a ‘ 0 ’, with OE0 set to ‘ 1 ’, the IE0 is an open-drain output with a 300 kOhm
pull-up to internal V DD .
OE0: Output Enable IO0 bit
Setting this bit to a ‘ 1 ’ will allow the PS700 to control NTC as either a push-pull (pp0 = 1 ) or
open-drain (pp0 = 0 ) output. If OE0 is a ‘ 0 ’, the NTC pin is tri-state (pp0 = 1 ) or pulled up to
internal V DD with a 300 kOhm resistor (pp0 = 0 ).
IE1: Input Enable IO1 bit
Setting this bit to a ‘ 1 ’ will enable IO1 (VC2) as a digital input. If IE1 is a ‘ 0 ’, the digital input
buffer on IO1 is powered down and IN1 will always read logic ‘ 0 ’.
IE0: Input Enable IO0 bit
Setting this bit to a ‘ 1 ’ will enable IO0 (NTC) as a digital input. If IE0 is a ‘ 0 ’ the digital input buffer
on IO0 is powered down and IN0 will always read logic ‘ 0 ’.
OUT1: Output Data GPIO1 bit
Setting this bit to a ‘ 0 ’ turns on the open-drain pull-down on IO1 (VC2) (forcing a logic ‘ 0 ’ on the
output). Setting this bit to a ‘ 1 ’ turns off the pull-down resistor.
OUT0: Output Data GPIO0 bit
If OE0 is a ‘ 1 ’, the logic value of OUT0 is driven onto the IO0 (NTC) pin by the PS700.
IN1: Input Data GPIO1 bit
Current logic state of the IO1 (VC2) pin (read-only).
IN0: Input Data GPIO0 bit
Current logic state of the IO0 (NTC) (read-only).
