INTERRUPT VECTOR REGISTER (I2CIVR)
R249 - Read / Write
Register Page: 20
Reset Value: Undefined
Bit 7:3 = V[7:3] Interrupt Vector Base Address .
User programmable interrupt vector bits. These
are the five more significant bits of the interrupt
vector base address. They must be set before en-
abling the interrupt features.
Bit 2:1 = EV[2:1] Encoded Interrupt Source .
These Read-Only bits are set by hardware accord-
ing to the interrupt source:
– 01: error condition detected
– 10: data received
– 11: peripheral ready to transmit
Bit 0 = Reserved.
Forced by hardware to 0.
RECEIVER DMA SOURCE ADDRESS POINTER
REGISTER (I2CRDAP)
R250 - Read / Write
Register Page: 20
Reset Value: Undefined
Bit 7:1 = RA[7:1] Receiver DMA Address Pointer .
I2CRDAP contains the address of the pointer (in
the Register File) of the Receiver DMA data
source when the DMA is selected between the
peripheral and the Memory Space. Otherwise,

this register.
Bit 0 = RPS Receiver DMA Memory Pointer Selec-
tor .
If memory has been selected for DMA transfer
(DDCRDC.RF/MEM = 0) then:
0: Select ISR register for Receiver DMA transfer
1: Select DMASR register for Receiver DMA trans-
RECEIVER DMA TRANSACTION COUNTER
REGISTER (I2CRDC)
R251 - Read / Write
Register Page: 20
Reset Value: Undefined
Bit 7:1 = RC[7:1] Receiver DMA Counter Pointer.
I2CRDC contains the address of the pointer (in the
Register File) of the DMA receiver transaction
counter when the DMA between Peripheral and
Memory Space is selected. Otherwise (DMA be-
tween Peripheral and Register File), this register
points to a pair of registers that are used as DMA
Address register and DMA Transaction Counter.
See Section 8.5.6.1 and Section 8.5.6.2 for more
details on the use of this register.
Bit 0 = RF/MEM Receiver Register File/ Memory
Selector.
