14.2.1 ROM Code Console

The console of the ROM code is a serial link to interact with the ROM code and its SAM-BA Monitors.

By default, the system communicates through FLEXCOM0 ( FLEXCOM0_IO0 on PA4, and FLEXCOM0_IO1 on PA5) configured in USART mode with the following attributes:

  • Baud rate: 115200 Baud
  • Data bits: 8
  • Parity: none
  • Stop bit: 1

With the GPBR[15] word, the baud rate can be reduced to 57600 if required.
