value = input_state(pin)
pin to read. Pins are defined in the devices .h file. The actual value is a
bit address. For example, port a (byte 5 ) bit 3 would have a value of
5*8+3 or 43 . This is defined as follows: #define PIN_A3 43 .
Bit specifying whether pin is high or low. A 1 indicates the pin is high and
a 0 indicates it is low.
This function reads the level of a pin without changing the direction of the
pin as INPUT() does.
