Address:
0x8082_0008 - Read/Write
Default:
0x0001_2492
Definition:
UART Data Register
Bit Descriptions:
672
RSVD:
Reserved. Unknown During Read.
Tx0_underflow:
when = 1, TX0 FIFO has underflowed.
Tx1_underflow:
when = 1, TX0 FIFO has underflowed.
Tx2_underflow:
when = 1, TX0 FIFO has underflowed.
Rx0_overflow:
when = 1, RX0 FIFO has overflowed and the FIFO pointer
is currently pointing at the last data received before the
overflow occurred.
Rx1_overflow:
when = 1, RX1 FIFO has overflowed and the FIFO pointer
is currently pointing at the last data received before the
overflow occurred.
Rx2_overflow:
when = 1, RX2 FIFO has overflowed and the FIFO pointer
is currently pointing at the last data received before the
overflow occurred.
Tx0_overflow:
when = 1, the tx0 FIFO is full and an attempt has been
made to write data to it by the APB or DMA. This bit is
cleared by writing a 0 to it.
