Bit No.
Name
Description
0
MIS (Read)
Modem Interrupt Status This bit is set if UARTMSINTR is active.
1
RIS (Read)
Receive Interrupt Status This bit is set if UARTRXINTR is active.
2
TIS (Read)
Transmit Interrupt Status This bit is set if UARTTXINTR is active.
3
RTIS (Read)
Receive Timeout Interrupt Status This bit is set if UARTRTINTR is active.
7 – 4
----- (Read)
Reserved
Value is undefined
7 – 0
----- (Write)
Writing to this register deletes the MIS bit irrespective of the value written.
UARTILPR
R/W
Addr.: 0x4000_2320 Default: 0x00
Description
UART IrDA low power counter registers
(not supported in the ERTEC 200)
Bit No.
Name
Description
7 – 0
ILPDVSR
8-bit low power divisor value
NOTE: The low power divisor is calculated according to the following formula:
F
UARTCLK
ILPDVSR
= ---------------------- - 1
FIrLPBAUD16 is nominally 1.8432 MHz
F
IrLPBAUD16
Zero is not a valid divisor.
