Introduction
2.7 Digital Peripherals
All GPIO pins support standard I/O operating modes - input/output mode select, strong drive high/low when in output mode, and selection of weak pullup or high
impedance (three-state) when in input mode.
Certain GPIO pin pairs have current sink capability that allows them to drive an open drain output (optical LED drive) based on a DAC output.
2.7.2
32-Bit Timer/Counters
The device includes four 32-bit timer/counter modules with the following features:
• 32-bit up/down count with auto reload mode
• One-shot or continuous operation mode
• Programmable 16-bit prescaler
• PWM output generation mode
• Capture/compare modes
• External input pin for timer input, clock gating or capture, limited to an input frequency of 1/4 of the peripheral clock
• Timer output pin
• Timer interrupt
Each 32-bit timer/counter module also has the option to be split into two separate 16-bit timers (dual 16-bit timer mode) for a possible total eight timers in the system.
Each 16-bit timer in this pair has the following features:
• 16-bit up/down count with auto reload mode
• One-shot or continuous operation mode
• Programmable 16-bit prescaler (setting is shared by both 16-bit timers in the pair)
• Timer interrupt (separate interrupt for each 16-bit timer in the pair)
2.7.3
Watchdog Timers
The
MAX32600
includes two independent watchdog timers (WDT) with window support. The watchdog timers run independently from each other and the processor
and have multiple clock source options for ensuring system stability. The watchdog uses a 32-bit timer with prescaler to generate the watchdog reset. When enabled,
the watchdog timers must be fed/reset prior to timeout or within a specified window of time if window mode is enabled. Failure to do so before the watchdog times
out will result in a watchdog reset event.
