FPB-RA0E1

The clock generation circuit Flexible Software Package (FSP) module supports runtime updates to clock settings, and in this example, the system clock source is switched to the low‑speed on‑chip oscillator. Using a lower‑frequency clock helps reduce current consumption.

Learn how to use the Event Link Controller, a hardware feature that routes event requests from one peripheral module to another, enabling direct cooperation without CPU intervention. In this example, an external interrupt is linked to driving a pin output. The Flexible Software Package (FSP) module supports configuring and operating the Event Link Controller.

Learn how the RA0E1 Fast Prototyping Board (FPB) operates in low‑power modes and returns to normal operation when a specified interrupt occurs. In this example, the interrupt source is the overflow of the 32‑bit Interval Timer (TML32). Use FSP to easily configure and manage low‑power mode behavior.

Learn how to use the low voltage detector (LVD) on the RA0E1 fast prototyping board (FPB). The LVD module monitors the voltage input to the VCC pin, with detection levels selectable through register settings at various thresholds. The r_lvd module in FSP provides full support for configuring and using the Low Voltage Detector.
