HD64F3644H Frequently Asked Questions (FAQs)

  • The recommended power-on sequence is to apply VCC first, followed by VDD, and then the clock signal. This ensures proper initialization of the device.
  • To use the JTAG interface for debugging, connect the TDI pin to the TDO pin of the next device in the scan chain. Ensure that the TCK pin is connected to the clock signal and the TMS pin is connected to the mode select signal.
  • The maximum frequency for the external clock input is 20 MHz. Exceeding this frequency may cause instability or incorrect operation.
  • The watchdog timer can be configured using the WDTCSR register. Set the WDTON bit to enable the watchdog timer, and set the WDP bits to select the timeout period.
  • The RST pin is an active-low reset input that resets the device when pulled low. It can be connected to a reset button or a reset generator IC.
