Multibuffer mode is selected when the MBUFMODE bit in SCIGCR1 is set to 1. In this mode, SCI sets the RXRDY bit after receiving the programmed number of data in the receive buffer, the complete frame. The error condition detection logic is similar to the single-buffer mode, except that this logic monitors for the complete frame. Like single-buffer mode, use the polling, DMA, or interrupt method to read the data. The RXRDY bit is automatically cleared after the new data in SCIRD has been read.
