Port 4
is a 2-bit quasi-bidirectional port with internal pull-up
arrangement. Port 4 pins that have 1’s written to them are
pulled high by the internal pull-up transistors and in that
state can be used as inputs. As inputs, port 4 pins being
externally pulled low will source current (
IIL, in the DC
characteristics) because of the internal pullup transistors.
The output latch corresponding to the secondary function
RXDC must be programmed to a one (1) for that function to
operate. The secondary functions are assigned to the two
pins of port 4 as follows (C505C and C505CA only) :
P4.0 / TXDC
Transmitter output of CAN controller
P4.1 / RXDC
Receiver input of CAN controller

XTAL2
Output of the inverting oscillator amplifier.
XTAL1
15
I
XTAL1
Input to the inverting oscillator amplifier and input to the
internal clock generator circuits.
To drive the device from an external clock source, XTAL1
should be driven, while XTAL2 is left unconnected. To
operate above a frequency of 16 MHz, a duty cycle of the
etxernal clock signal of 50 % should be maintained.
Minimum and maximum high and low times as well as rise/
fall times specified in the AC characteristics must be
observed.
