Debug UART Interface
The RZ/G1C SBC supports Debug UART interfaces on Expansion connector3. RZ/G1
C CPU’s SCIF1 controller is used
for Debug UART. If Debug UART interface is not required, then same SCIF1 can be used for Data UART interface.
The RZ/G1C
CPU’s SCIF module has two 16
-stage FIFO buffers separately for transmission and reception, which
enables fast, efficient, and uninterrupted full duplex communication. It has On-chip baud rate generator that allows
any bit rate to be selected. Also it supports DMA transfers.
