This module can be added to the Stacks tab via New Stack > Timers > Timer, Low-Power (r_agt). If selected code for outputting a waveform to a pin is included in the build.Įnable input support to use pulse width measurement mode, pulse period measurement mode, or input from P402, P402, or AGTIO.Ĭonfigurations for Timers > Timer, Low-Power (r_agt) If selected code for parameter checking is included in the build. The following build time configurations are defined in fsp_cfg/r_agt_cfg.h: The AGT runs off PCLKB, LOCO, or subclock with a configurable divider up to 8 for PCLKB or up to 128 for LOCO or subclock. It can also be configured to count ELC events or external pulses. The GPT runs off PCLKD with a configurable divider up to 1024.
All currently supported MCUs have at least 7 GPT channels.Īll MCUs have at least one 32-bit GPT timer. The number of GPT channels is device specific. The AGT can operate in all low power modes (when count source is LOCO or subclock). When selecting between them, consider these factors: RA MCUs have two timer peripherals: the General PWM Timer (GPT) and the Asynchronous General Purpose Timer (AGT). APIs are provided to get the current timer status and counter value.APIs are provided to get the current period, source clock frequency, and count direction.APIs are provided to start, stop, and reset the counter.Supports measuring pulse width or pulse period.Supports debounce filter on AGTIO pins.Supports counting based on an external clock input to AGTIO.Supports runtime reconfiguration of duty cycle in PWM mode.Supports runtime reconfiguration of period.Configurable clock source, including PCLKB, LOCO, SUBCLK, and external sources input to AGTIO.Configurable period (counts per timer cycle).Supports periodic mode, one-shot mode, and PWM mode.The AGT module has the following features: This module implements the Timer Interface.
