SPIxBUFL: SPIx BUFFER REGISTER LOW

R/W-0

DATA<15:8>

bit 15

bit 8

R/W-0

DATA<7:0>

bit 7

bit 0

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown

bit 15-0

DATA<15:0>: SPIx FIFO Data bits

When the MODE<32,16> or WLENGTH<4:0> bits select 16 to 9-bit data, the SPIx only uses

DATA<15:0>. When the MODE<32,16> or WLENGTH<4:0> bits select 8 to 2-bit data, the SPIx only uses

DATA<7:0>.

SPIxBUFH: SPIx BUFFER REGISTER HIGH

R/W-0

DATA<31:24>

bit 15

bit 8

R/W-0

DATA<23:16>

bit 7

bit 0

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown

bit 15-0

DATA<31:16>: SPIx FIFO Data bits

When the MODE<32,16> or WLENGTH<4:0> bits select 32 to 25-bit data, the SPIx uses DATA<31:16>.

When the MODE<32,16> or WLENGTH<4:0> bits select 24 to 17-bit data, the SPIx only uses

DATA<23:16>.
