Function
Port 5 is a 6-bit input-only port with Schmitt-Trigger
characteristics. The pins of Port 5 also serve as timer inputs:
P5.10
P5.11
P5.12
P5.13
P5.14
P5.15
XTAL1:
XTAL2:
To clock the device from an external source, drive XTAL1,
while leaving XTAL2 unconnected. Minimum and maximum
high/low and rise/fall times specified in the AC Characteristics
must be observed.
Port 3 is a 15-bit (P3.14 is missing) bidirectional I/O port. It is
bit-wise programmable for input or output via direction bits.
For a pin configured as input, the output driver is put into high-
impedance state. Port 3 outputs can be configured as push/
pull or open drain drivers.
The following Port 3 pins also serve for alternate functions:
P3.1
P3.2
P3.3
P3.4
P3.5
P3.6
