Siemens ERTEC200

UARTIIR/UARTICR R/W Addr.: 0x4000_231C Default: 0x00

Description UART interrupt identification register (read)

UART interrupt clear register (write)

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:

FUARTCLK

ILPDVSR = ---------------------- - 1 FIrLPBAUD16 is nominally 1.8432 MHz

FIrLPBAUD16

Zero is not a valid divisor.
