16-Bit Microcontroller with Infrared Module
MAXQ61C
______________________________________________________________________________________ 19
General-Purpose I/O
The microcontroller provides port pins for general-pur-
pose I/O that have the following features:
CMOS output drivers
Schmitt trigger inputs
Optional weak pullup to VDD when operating in input
mode
While the microcontroller is in a reset state, all port pins
become high impedance with both weak pullups and
input buffers disabled, unless otherwise noted.
From a software perspective, each port appears as a
group of peripheral registers with unique addresses.
Special function pins can also be used as general-pur-
pose I/O pins when the special functions are disabled.
For a detailed description of the special functions avail-
able for each pin, refer to the MAXQ610 User’s Guide.
On-Chip Oscillator
An external quartz crystal or a ceramic resonator can be
connected between HFXIN and HFXOUT, as illustrated
in Figure 9.
Noise at HFXIN and HFXOUT can adversely affect on-
chip clock timing. It is good design practice to place the
crystal and capacitors near the oscillator circuitry and
connect HFXIN and HFXOUT to ground with a direct
short trace. The typical values of external capacitors vary
with the type of crystal to be used and should be initially
selected based on load capacitance as suggested by
the manufacturer.
