Configuration
Conï¬gured to loop-back mode using a bit rate of 1Mbit/s
Conï¬gured to master mode, continuously transmit data
(0x55 or 0xAA) at 1Mbit/s
Conï¬gured into loop mode, continuously transmit data
(0x55) at speed of 57600 baud
Conï¬gured to toggle its pins at the rate of 40kHz
The peripheral is conï¬gured to operate at its maximum
speciï¬ed frequency and to continuously convert voltages on
all input channels in sequence.
The module is enabled and the comparators are conï¬gured
to trigger in outside range.The range covers all the code
executed by the core.
