SPRS230L –OCTOBER 2003 –REVISED DECEMBER 2009

The SPI port operation is configured and controlled by the registers listed in Table 4-10through Table 4-13.

Table 4-10. SPI-A Registers

NAME	ADDRESS	SIZE (x16)	DESCRIPTION (1)
SPICCR	0x7040	1	SPI-A Configuration Control Register

SPICTL	0x7041	1	SPI-A Operation Control Register

SPISTS	0x7042	1	SPI-A Status Register

SPIBRR	0x7044	1	SPI-A Baud Rate Register

SPIRXEMU	0x7046	1	SPI-A Receive Emulation Buffer Register

SPIRXBUF	0x7047	1	SPI-A Serial Input Buffer Register

SPITXBUF	0x7048	1	SPI-A Serial Output Buffer Register

SPIDAT	0x7049	1	SPI-A Serial Data Register
