R5F21238KFP#U1 Frequently Asked Questions (FAQ)
-
The recommended power-on sequence is to apply VCC first, followed by AVCC, and then the clock signal. This ensures proper initialization of the internal voltage regulators and prevents latch-up.
-
The clock settings can be configured using the Clock Control Register (CKCR). The register allows selection of the clock source, clock frequency, and clock mode. Refer to the datasheet for specific register settings and bit assignments.
-
The VCAP pin is used to connect an external capacitor for the internal voltage regulator. This capacitor helps to stabilize the internal voltage and ensure proper operation of the microcontroller.
-
The ADC on the R5F21238KFP#U1 can be used by configuring the ADC Control Register (ADCCR) and the ADC Data Register (ADCDR). The ADC can be triggered by a software trigger or an external trigger signal.
-
The maximum operating frequency of the R5F21238KFP#U1 is 32 MHz. However, the actual operating frequency may be limited by the clock source and the system design.
