and is reset to 0 when the data transfer is complete. Inspect TRBS to determine whether the transmit
circuit is operating or at standby.
D1
RDRY: Receive Data Ready Flag
Indicates that the receive data buffer contains valid received data.
1 (R):

0 (R):
Buffer empty (default)
RDRY is set to 1 when received data is loaded into the receive data buffer and is reset to 0 when all data
has been read from the receive data buffer.
D0
TDBE: Transmit Data Buffer Empty Flag
Indicates the state of the transmit data buffer.
