____________________________________________________________________
Power-On Reset
An internal power-on reset circuit enhances system reli-
ability. This circuit forces the device to perform a
power-on reset whenever a rising voltage on VDDIO
climbs above approximately 1.8V. At this point the fol-
lowing events occur:
All registers and circuits enter their reset state
The POR flag (WDCN.7) is set to indicate the source
of the reset
The ring oscillator becomes the clock source and
Code execution begins at location 8000h
Watchdog Timer Reset
The watchdog timer functions are described in the
MAXQ Family User’s Guide. Execution resumes at loca-
tion 8000h following a watchdog timer reset.
External System Reset
Asserting the external RESET pin low causes the device
to enter the reset state. The external reset functions as
described in the
MAXQ Family User’s Guide. Execution
resumes at location 8000h after the RESET pin is
released.
I/O Ports
The microcontroller uses the type C and type D bidirec-
tional I/O ports described in the
MAXQ Family User’s
Guide. The use of two port types allows for maximum
flexibility when interfacing to external peripherals. Each
port has eight independent, general-purpose I/O pins
and three configure/control registers. Many pins support
alternate functions such as timers or interrupts, which are
enabled, controlled, and monitored by dedicated periph-
eral registers. Using the alternate function automatically
converts the pin to that function.
Type-C port pins have Schmitt Trigger receivers and
full CMOS output drivers, and can support alternate
functions. The pin is either tri-stated or weak pullup
when defined as an input, dependent on the state of
the corresponding bit in the output register.
Type-D port pins have Schmitt Trigger receivers and
full CMOS output drivers, and can support alternate
functions. The pin is either tri-stated or weak pullup
when defined as an input, dependent on the state of
the corresponding bit in the output register. All type-D
pins also have interrupt capability.
