TRANSMITTER
POINTER REGISTER (I2CTDAP)
R252 - Read / Write
Register Page: 20 (I2C_0) or 22 (I2C_1)
Reset Value: Undefined
Bits 7:1= TA[7:1] Transmit DMA Address Pointer.
I2CTDAP contains the address of the pointer (in
the Register File) of the Transmitter DMA data
source when the DMA between the peripheral and
the Memory Space is selected. Otherwise (DMA
between the peripheral and Register file), this reg-
ister has no meaning.

Bit 0 = TPS Transmitter DMA Memory Pointer Se-
lector.
If memory has been selected for DMA transfer
(I2CTDC.RF/MEM = 0) then:
0: Select ISR register for transmitter DMA transfer
1: Select DMASR register for transmitter DMA

R253 - Read / Write
Register Page: 20 (I2C_0) or 22 (I2C_1)
Reset Value: Undefined
Bits 7:1 = TC[7:1] Transmit DMA Counter Pointer.
I2CTDC contains the address of the pointer (in the
Register File) of the DMA transmitter transaction
counter when the DMA between Peripheral and
Memory Space is selected. Otherwise, if the DMA
between Peripheral and Register File is selected,
this register points to a pair of registers that are
used as DMA Address register and DMA Transac-
tion Counter.
See
more details on the use of this register.
Bit 0 = RF/MEM Transmitter Register File/ Memo-
ry Selector.
0: DMA from Memory
1: DMA from Register file

Reset Value: 0000 0000 (00h)
Bits 7:2 = Reserved. Must always be cleared.
Bits 1:0 = CC[8:7] 9-bit divider programming
Implementation of a programmable clock divider.
These bits and the CC[6:0] bits of the I2CCCR reg-
ister select the speed of the bus (F

I2CCCR register.
They are not cleared when the interface is disa-
bled (I2CCCR.PE=0).
