INTERRUPT VECTOR REGISTER (I2CIVR)
R249 - Read / Write
Register Page: 20 (I2C_0) or 22 (I2C_1)
Reset Value: Undefined
Bits 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.
Bits 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 (I2C_0) or 22 (I2C_1)
Reset Value: Undefined
Bits 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,

If memory has been selected for DMA transfer
(I2CRDC.RF/MEM = 0) then:

RECEIVER DMA TRANSACTION COUNTER
REGISTER (I2CRDC)
R251 - Read / Write
Register Page: 20 (I2C_0) or 22 (I2C_1)
Reset Value: Undefined
Bits 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.
