for normal operation, pin PD must be LOW
pin R/W = HIGH selects the read operation
pin R/W = LOW selects the write operation
this pin has an internal pull-up resistor
this pin has an internal pull-up resistor
the 8-bit bidirectional data bus (3-state) transfers data
between the microcontroller and the PCF2119x
pin DB7 may be used as the busy flag, signalling that
internal operations are not yet completed
4-bit operations the 4 higher order lines DB7 to DB4 are
used, DB3 to DB0 must be left open-circuit
data bus line DB3 has an alternative function (SA0) as the
I
each data line has its own internal pull-up resistor
when the on-chip oscillator is used this pin must be
connected to V
