I/O
Port 9
is an 8-bit quasi-bidirectional I/O port with internal pullup
resistors. Port 9 pins that have 1's written to them are
pulled high by the internal pullup resistors, and in that
state can be used as inputs. As inputs, port 9 pins being
externally pulled low will source current (
I
IL
, in the DC
characteristics) because of the internal pullup resistors.
Port 9 can also be switched into a bidirectional mode, in
which CMOS levels are provided. In this bidirectional
mode, each port 1 pin can be programmed individually
as input or output.
Port 9 also serves alternate compare functions. The out-
put 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 9 as follows :
P9.0-P9.7 CC10-CC17
Compare/capture channel 0-7

XTAL2
is the input to the inverting oscillator amplifier and input
to the internal clock generator circuits.
When supplying the C509-L with an external clock
source, XTAL2 should be driven, while XTAL1 is left
unconnected. A duty cycle of 0.4 to 0.6 of the clock
signal is required. Minimum and maximum high and low
times as well as rise/fall times specified in the AC
characteristics must be observed.
