@/portd-pin-read
This patch reads the value of the PORTD registry and outputs the bool value of the selected pin.
UPDpulse
Signals when the code should run.
PINnumber
The number that represents each pin of the target hardware on PORTD.
Selects the pin state that will be read.
Pin 0-7
ERRpulse
indicates when a pin input value is not accepted.
SIGboolean
Outputs the selected pin reg value in bool
VALbyte
Outputs the PORTD reg value
