The SPI port operation is configured and controlled by the registers listed in Table 4-6 and Table 4-7.

Table 4-6. SPI-A Registers

NAME ADDRESS SIZE (x16) EALLOW PROTECTED DESCRIPTION

(1)

SPICCR 0x7040 1 No SPI-A Configuration Control Register

SPICTL 0x7041 1 No SPI-A Operation Control Register

SPISTS 0x7042 1 No SPI-A Status Register

SPIBRR 0x7044 1 No SPI-A Baud Rate Register

SPIRXEMU 0x7046 1 No SPI-A Receive Emulation Buffer Register

SPIRXBUF 0x7047 1 No SPI-A Serial Input Buffer Register

SPITXBUF 0x7048 1 No SPI-A Serial Output Buffer Register

SPIDAT 0x7049 1 No SPI-A Serial Data Register

SPIFFTX 0x704A 1 No SPI-A FIFO Transmit Register

SPIFFRX 0x704B 1 No SPI-A FIFO Receive Register

SPIFFCT 0x704C 1 No SPI-A FIFO Control Register

SPIPRI 0x704F 1 No SPI-A Priority Control Register

(1) Registers in this table are mapped to Peripheral Frame 2. This space only allows 16-bit accesses. 32-bit accesses produce undefined

results.

SPIBRR 0x7744 1 No SPI-B Baud Rate Register

SPIRXEMU 0x7746 1 No SPI-B Receive Emulation Buffer Register

SPIRXBUF 0x7747 1 No SPI-B Serial Input Buffer Register

SPITXBUF 0x7748 1 No SPI-B Serial Output Buffer Register

SPIDAT 0x7749 1 No SPI-B Serial Data Register

SPIFFTX 0x774A 1 No SPI-B FIFO Transmit Register

SPIFFRX 0x774B 1 No SPI-B FIFO Receive Register

SPIFFCT 0x774C 1 No SPI-B FIFO Control Register

SPIPRI 0x774F 1 No SPI-B Priority Control Register
