11-40 GPIOs, depending on configuration
5-V-tolerant input/outputs
Programmable interrupt generation as either edge-triggered or level-sensitive
Bit masking in both read and write operations through address lines
Programmable control for GPIO pad configuration:
•
•
•
•
•
On-chip Low Drop-Out (LDO) voltage regulator, with programmable output user-adjustable
from 2.25 V to 2.75 V
Low-power options on controller: Sleep and Deep-sleep modes
Low-power options for peripherals: software controls shutdown of individual peripherals
Output PWM signal is constructed based on actions taken as a result of the counter and
PWM comparator output signals
Produces two independent PWM signals
Produces two PWM signals with programmable dead-band delays suitable for driving a
half-H bridge
Can be bypassed, leaving input PWM signals unmodified
PWM output enable of each PWM signal
Optional output inversion of each PWM signal (polarity control)
Optional fault handling for each PWM signal
Synchronization of timers in the PWM generator blocks
Synchronization of timer/comparator updates across the PWM generator blocks
Interrupt status summary of the PWM generator blocks
Weak pull-up or pull-down resistors
2-mA, 4-mA, and 8-mA pad drive
Slew rate control for the 8-mA drive
Open drain enables
Digital input enables
