The transmit FIFO is an 8-bit wide, 16-location deep FIFO memory buffer. CPU data
written across the APB interface is stored in the FIFO until it is read out by the
transmit logic. The transmit FIFO can be disabled to act like a one-byte holding
register.
The receive FIFO is a 12-bit wide, 16-location deep, FIFO memory buffer. Received
data and corresponding error bits are stored in the receive FIFO by the receive logic
until they are read out by the CPU across the APB interface. The receive FIFO can be
disabled to act like a one-byte holding register.
