The mini UART has smaller FIFOs. Combined with the lack of ow control, this makes it more prone to
losing characters at higher baudrates. It is also generally less capable than the PL011, mainly due to its baud
rate link to the VPU clock speed.
The particular deficiencies of the mini UART compared to the PL011 are :
·No break detection
·No framing errors detection
·No parity bit
·No receive timeout interrupt
·No DCD, DSR, DTR or RI signals
