Function
Port 6
is a bidirectional I/O port with internal
pull-up resistors. Port 6 pins that have
1 s written to them are pulled high by
the internal pull-up resistors, and in that
state can be used as inputs. As inputs,
port 6 pins being externally pulled low
will source current (I
DC characteristics) because of the
internal pull-up resistors. Port 6 also
contains the external A/D converter
control pin and the transmit and receive
pins for serial channel 1. The output
latch corresponding to a secondary
function must be programmed to a one
(1) for that function to operate.
The secondary functions are assigned
to the pins of port 6, as follows:
– ADST (P6.0): external A/D converter
– R D1 (P6.1): receiver data input of
– T D1 (P6.2): transmitter data output
Port 8
is a 4-bit unidirectional input port. Port
pins can be used for digital input, if
voltage levels meet the specified input
high/low voltages, and for the higher
4-bit of the multiplexed analog inputs of
the A/D converter, simultaneously
