17.5.5. Issuing Timing of Reset Signal
The above figure is a timing chart that shows the RESETN signal that is input to the device by setting bit [11] of the System
Control Register to “1”. As you can see from the above timing chart, the system is configured so you can send an interrupt
signal to the microcontroller simultaneous to automatically clearing the above bit when the time set by the Host Reset Timer
Register elapses.
