/* UART0
|
|
*
|
|
* The control MCU acts as a board controller (BC). There is a UART
|
|
* connection between the EFM and the BC. The connection is made by
|
|
* setting the EFM_BC_EN (PD13) line high. The EFM can then use the BSP to
|
|
* send commands to the BC. When EFM_BC_EN is low, EFM_BC_TX and EFM_BC_RX
|
|
* can be used by other applications.
