Bit 6: TSRE. In 16450 mode, when TBR and TSR are both empty, this bit will be set to a logical 1. In
Bit 5: TBRE. In 16450 mode, when a data character is transferred from TBR to TSR, this bit will be set
Bit 4: SBD. This bit is set to a logical 1 to indicate that received data are kept in silent state for a full
Bit 3: NSER. This bit is set to a logical 1 to indicate that the received data have no stop bit. In 16550
Bit 2: PBER. This bit is set to a logical 1 to indicate that the parity bit of received data is wrong. In
Bit 1: OER. This bit is set to a logical 1 to indicate received data have been overwritten by the next
Bit 0: RDR. This bit is set to a logical 1 to indicate received data are ready to be read by the CPU in
6.2.3
This register controls the pins of the UART used for handshaking peripherals such as modem, and
controls the diagnostic mode of the UART.
16550 mode, if the transmit FIFO and TSR are both empty, it will be set to a logical 1. Other
than in these two cases, this bit will be reset to a logical 0.
to a logical 1. If ETREI of ICR is a logical 1, an interrupt will be generated to notify the CPU to
write the next data. In 16550 mode, this bit will be set to a logical 1 when the transmit FIFO is
empty. It will be reset to a logical 0 when the CPU writes data into TBR or FIFO.
