Revision A1
Bit 0: RDR. This bit is set to a logical 1 to indicate received data are ready to be read by the CPU in
the RBR or FIFO. After no data are left in the RBR or FIFO, the bit will be reset to a logical 0.
4.2.3 Handshake Control Register (HCR) (Read/Write)
This register controls the pins of the UART used for handshaking peripherals such as modem, and
controls the diagnostic mode of the UART.

Notes:
Bit 4: When this bit is set to a logical 1, the UART enters diagnostic mode by an internal loopback,
as follows:
(1) SOUT is forced to a logical 1, and SIN is isolated from the communication link instead of
the
TSR.
(2) Modem output pins are set to their inactive state.
(3) Modem input pins are isolated from the communication link and connect internally as DTR
(bit 0 of HCR)
DSR, RTS ( bit 1 of HCR)
CTS, Loopback RI input ( bit 2 of HCR)
RI
and IRQ enable ( bit 3 of HCR)
DCD.
Aside from the above connections, the UART operates normally. This method allows the
CPU to test the UART in a convenient way.
Bit 3: The UART interrupt output is enabled by setting this bit to a logic 1. In the diagnostic mode this
bit is internally connected to the modem control input
DCD
.
Bit 2: This bit is used only in the diagnostic mode. In the diagnostic mode this bit is internally
connected to the modem control input
RI
.
Bit 1: This bit controls the
RTS
output. The value of this bit is inverted and output to
RTS
.
Bit 0: This bit controls the
DTR
output. The value of this bit is inverted and output to
DTR
.
