Datasheet

• Edge-triggered on rising, falling, or both
• Level-sensitive on High or Low values
– Bit masking in both read and write operations through address lines
– Can initiate an ADC sample sequence
– Pins configured as digital inputs are Schmitt-triggered.
– Programmable control for GPIO pad configuration
• Weak pull-up or pull-down resistors
• 2-mA, 4-mA, and 8-mA pad drive for digital communication; up to four pads can be
configured with an 18-mA pad drive for high-current applications
• Slew rate control for the 8-mA drive
• Open drain enables
• Digital input enables
■ General-Purpose Timers
– Four General-Purpose Timer Modules (GPTM), each of which provides two 16-bit
timers/counters. Each GPTM can be configured to operate independently:
• As a single 32-bit timer
• As one 32-bit Real-Time Clock (RTC) to event capture
• For Pulse Width Modulation (PWM)
• To trigger analog-to-digital conversions
– 32-bit Timer modes
• Programmable one-shot timer
• Programmable periodic timer
• Real-Time Clock when using an external 32.768-KHz clock as the input
• User-enabled stalling when the controller asserts CPU Halt flag during debug
• ADC event trigger
– 16-bit Timer modes
• General-purpose timer function with an 8-bit prescaler (for one-shot and periodic modes
only)
• Programmable one-shot timer
• Programmable periodic timer
