Description

Receive FIFO Data Register H

Fields

RDATH

Serial receive data(b8) (Valid only in asynchronous mode(including multi-processor) or clock synchronous mode, and FIFO selected)

MPB

Multi-processor bit flag (Valid only in asynchronous mode with SMR.MP=1 and FIFO selected) It can read multi-processor bit corresponded to serial receive data(RDATA[8:0])

0 (0): Data transmission cycles

1 (1): ID transmission cycles

DR

Receive data ready flag (It is same as SSR.DR)

0 (0): Receiving is in progress, or no received data has remained in FRDRH and FRDRL after normally completed receiving.

1 (1): Next receive data has not been received for a period after normal completed receiving.

PER

Parity error flag

0 (0): No parity error occurred at the first data of FRDRH and FRDRL

1 (1): A parity error has occurred at the first data of FRDRH and FRDRL

FER

Framing error flag

0 (0): No framing error occurred at the first data of FRDRH and FRDRL

1 (1): A framing error has occurred at the first data of FRDRH and FRDRL

ORER

Overrun error flag (It is same as SSR.ORER)

0 (0): No overrun error occurred

1 (1): An overrun error has occurred

RDF

Receive FIFO data full flag (It is same as SSR.RDF)

0 (0): The quantity of receive data written in FRDRH and FRDRL falls below the specified receive triggering number.

1 (1): The quantity of receive data written in FRDRH and FRDRL is equal to or greater than the specified receive triggering number.

Reserved

This bit is read as 0.
