TABLE 29 - DIRECT MAPPED MODULE A, MODULE B, MODULE C, AND
MODULE D REGISTERS
TABLE 30 - DIRECT MAPPED OTHER REGISTERS
9.2 Direct access registers
The direct access registers are in the directly-addressed access space.
Direct access registers are more quickly accessed, and serve the needs of
interrupts and the indirect register access.

7:1
The SPI-3 data capture control register has read and write access in the direct
register access space. Write a zero to DATA_AVAILABLE to clear the transfer.
The mcroprocessor uses these registers to capture data froma SPI-3 ingress.
The SPI-3 data capture control register for SPI-3 port A is register 0x00.
The SPI-3 data capture control register for SPI-3 port B is register 0x08.
The SPI-3 data capture control register for SPI-3 port C is register 0x10.
The SPI-3 data capture control register for SPI-3 port D is register 0x18.
The bit field of the SPI-3 data capture control register is described.

SPI-3 data capture register
The SPI-3 data capture register has read-only access in the direct register
access space. The mcroprocessor uses these registers to capture data from
a SPI-3 ingress.
The SPI-3 data capture register for SPI-3 port A is register 0x01.
The SPI-3 data capture register for SPI-3 port B is register 0x09.
The SPI-3 data capture register for SPI-3 port C is register 0x11.
The SPI-3 data capture register for SPI-3 port D is register 0x19.
The bit field of the SPI-3 data capture register is described.
DATA
The SPI-3 capture data buffer is read fromthis field.
