RM57 SCI(uart) FIFO

Akshay Immanuel

Does the SCI module(uart) have a receive or transmit FIFO (if yes,whats the FIFO size)

Does the received or transmitted data go directly into the double buffers(if yes, so a max of only 2 bytes can be received before an overflow occurs if it is not serviced on time?)

For the SCI receive, the data will first go to the receive shift register. When the complete data is is received, the received data will be moved to the receive data register (single buffer mode) or the buffer (multi-buffle mode). Please see the TRM for more details.

Thanks and regards,

I have gone through the TRM.
They have mentioned about double buffering...
There is no mention about multi buffer in RM57 TRM

Thanks
