R/W
OTPC_MODE_PRG_ Selects the source that is connected to the prg_port port of
0x0
PORT_MUX
the controller.
00 - {16'd0, BANDGAP_REG[15:0]}
01 - {RF_RSSI_COMP_CTRL_REG[15:0], 8'd0,
RFIO_CTRL1_REG{7:0]}
10 - {3'd0, RF_LNA_CTRL3_REG[4:0],
RF_LNA_CTRL2_REG[11:0], RF_LNA_CTRL1_REG[11:0]}
11 - {28'd0, RF_VCO_CTRL_REG[3:0]}

R/W
OPTC_MODE_PRG_ Defines the timing that will be used for all the programming
FAST
activities (APROG, MPROG and TWR)
0 - Selects the normal timing
1 - Selects the fast timing

R/W
OTPC_MODE_PRG_ Selects an alternative data source for the programming of
0x0
PORT_SEL
the OTP macrocells, when the controller is configured in
APROG mode.
0 - The fifo will be used as the data source. The fifo will be
filled with a way defined by the register
OTPC_MODE_USE_DMA. The number of words that will be
programmed is defined by OTPC_NWORDS.
1 - Only one word will programmed. The value of the word is
contained in the prg_port port of the controller. The values of
the registers OTPC_MODE_USE_DMA, OTPC_NWORDS
and the contents of the FIFO will not be used.

R/W
OTPC_MODE_TWO
_CC_ACC
Defines the duration of each read from the OTP macrocells.
0 - Reads 16 bits of data every one clock cycle.
1 - Reads 16 bits of data every two clock cycles.

OTPC_MODE_FIFO
_FLUSH
Writing 1, removes any content from the FIFO. This bit
returns automatically to 0.

0x0
OTPC_MODE_USE_
DMA
Selects the use of the dma, when the controller is configured
in one of the modes: AREAD or APROG.
0 - DMAis not used. The data should be transfered from/to
controller through OTPC_FFPRT_REG
1 - DMA is used. Data transfers from/to controller are per-
formed automatically. The AHB base address should be con-
figured in OTPC_AHBADR_REG before the selection of the
mode.
If programming of the OTPC_MODE_REG is performed
through the serial interface,the OTPC_MODE_USE_DMA
will be set to 0 automatically.
If the controller is in APROG mode and the
OTPC_MODE_PRG_PORT_SEL is enabled, the dma will
stay inactive.
