MULTIPROTOCOL SERIAL COMMUNICATIONS INTERFACE (Cont’d)
INTERRUPT MASK REGISTER (IMR)
R246 - Read/Write
Reset value: 0xx00000
Bit 7 = BSN: Buffer or shift register empty inter-
rupt.
This bit selects the source of the transmitter regis-
ter empty interrupt.
0: Select a Shift Register Empty as source of a
1: Select a Buffer Register Empty as source of a
Bit 6 = RXEOB: Received End of Block.
This bit is set by hardware only and must be reset
by software. RXEOB is set after a receiver DMA
cycle to mark the end of a data block.
0: Clear the interrupt request.
1: Mark the end of a received block of data.
Bit 5 = TXEOB: Transmitter End of Block.
This bit is set by hardware only and must be reset
by software. TXEOB is set after a transmitter DMA
cycle to mark the end of a data block.
0: Clear the interrupt request.
1: Mark the end of a transmitted block of data.
