MIXED SIGNAL MICROCONTROLLER
SLAS547A -- JUNE 2007 -- REVISED NOVEMBER 2007
digital I/O
There are up to six 8-bit I/O ports implemented鈥攑orts P1 through P6.

All individual I/O bits are independently programmable.
Any combination of input, output, and interrupt conditions is possible.
Edge-selectable interrupt input capability for all eight bits of ports P1 and P2.
Read/write access to port-control registers is supported by all instructions.
Each I/O has an individually programmable pullup/pulldown resistor.
watchdog timer + (WDT+)
The primary function of the WDT+ module is to perform a controlled system restart after a software problem
occurs. If the selected time interval expires, a system reset is generated. If the watchdog function is not needed
in an application, the module can be configured as an interval timer and can generate interrupts at selected time
intervals.
hardware multiplier
The multiplication operation is supported by a dedicated peripheral module. The module performs 16脳16,
16脳8, 8脳16, and 8脳8 bit operations. The module is capable of supporting signed and unsigned multiplication
as well as signed and unsigned multiply and accumulate operations. The result of an operation can be accessed
immediately after the operands have been loaded into the peripheral registers. No additional clock cycles are
required.
timer_A3
Timer_A3 is a 16-bit timer/counter with three capture/compare registers. Timer_A3 can support multiple
capture/compares, PWM outputs, and interval timing. Timer_A3 also has extensive interrupt capabilities.
Interrupts may be generated from the counter on overflow conditions and from each of the capture/compare
registers.
