Technical data subject to change
Version 1.0
when UART error interrupt is asserted.
31dt3 <unused>
00000000h r
Reserved, do not modify, read as zero.
Register:
UARTTCR
Address:
80h
Bits:
31dt0
Reset value:
0h
Attributes: r (w)
Description:
Test control register
(for integration test)
Bit
Identifier

Attr.
Function / Description
0
ITEN
0h
r w
Integration test enable. When this bit is
1, the UART is placed in integration
test mode, otherwise it is in normal
mode.
1
TESTFIFO
0h
r w
Test FIFO enable. When this bit it 1, a
write to the UARTTDR writes data into
the receive FIFO, and reads from the
UARTTDR reads data out of the
transmit FIFO.
When this bit is 0, data cannot be read
directly from the transmit FIFO or
written directly to the receive FIFO
(normal operation).
2
SIRTEST
0h
r w
SIR test enable. Setting this bit to 1
enables the receive data path during
IrDa transmission (testing
requires the SIR to be configured in
full-duplex mode). This bit must be set
to 1 to enable SIR system loop back
testing, when the normal mode control
register UARTCR bit 7, Loop Back
Enable (LBE) has been set to 1.
Clearing this bit to 0 disables the re-
ceive logic when the SIR is transmit-
ting (normal operation). This bit de-
faults to 0 for normal operation (half-
duplex peration).
31dt3 <unused>
00000000h r
Reserved, unpredictable when read.
