Peripheral Simulation

For Nuvoton W77E516 — Ring Oscillator

Simulation support for this peripheral or feature is comprised of:

  • VTREGs (Virtual Target Registers) which support I/O with the peripheral.

These simulation capabilities are described below.

Data Type: unsigned long

The RING VTREG contains the frequency of the internal ring oscillator (in Hertz) which may be used to drive the microcontroller. You may change the value of RING using the command window. For example:


You may also output the current value of RING using the following:
