MULTIPROTOCOL SERIAL COMMUNICATIONS INTERFACE (SCI-M)
MULTIPROTOCOL SERIAL COMMUNICATIONS INTERFACE (Cont’d)
INTERRUPT VECTOR REGISTER (S_IVR)
R244 - Read/Write
Reset value: undefined
Bit 7:3 = V[7:3]: SCI Interrupt Vector Base Ad-
dress.
User programmable interrupt vector bits for trans-
mitter and receiver.
Bit 2:1 = EV[2:1]: Encoded Interrupt Source.
Both bits EV2 and EV1 are read only and set by
hardware according to the interrupt source.
Bit 0 = D0: This bit is forced by hardware to 0.

ADDRESS/DATA COMPARE REGISTER (ACR)
R245 - Read/Write
Reset value: undefined
Bit 7:0 = AC[7:0]: Address/Compare Character.
With either 9th bit address mode, address after
break mode, or character search, the received ad-
dress will be compared to the value stored in this
register. When a valid address matches this regis-
ter content, the Receiver Address Pending bit
(RXAP in the S_ISR register) is set. After the
RXAP bit is set in an addressed mode, all received
data words will be transferred to the Receiver Buff-
er Register.
