Transmit Parity.
TPRTY indicates odd parity for the TDAT
bus. TPRTY is valid only when a channel
asserts either TENB or TSX. Odd parity is
the default configuration; however, even
parity can be selected (see Table 146 “SPI3
Transmit and Global Configuration
($0x700)” on page 212).
32-bit Multi-PHY mode: TPRTY_0 is the
parity bit covering all 32 bits.
4 x 8 Single-PHY mode: TPRTY_0:3 bits
correspond to the respective TDAT[3:0]_n
channels.

Transmit Write Enable.
TENB_0:3 asserted causes an attached
PHY to process TDAT[n], TMOD, TSOP,
TEOP and TERR signals.
32-bit Multi-PHY mode: TENB_0 is the
enable bit for all 32 bits.
4 x 8 Single-PHY mode: TENB_0:3 bits
correspond to the respective TDAT[3:0]_n
channels and their associated control and
status signals.

Transmit Error.
TERR indicates that there is an error in the
current packet. TERR is valid when
simultaneously asserted with TEOP and
TENB.
32-bit Multi-PHY mode: TERR_0 is the bit
asserted for all 32 bits.
4 x 8 Single-PHY mode: Each bit of
TERR_0:3 corresponds to the respective
TDAT[3:0]_n channel.

Transmit Start-of-Packet.
TSOP indicates the start of a packet and is
valid when asserted simultaneously with
TENB.
32-bit Multi-PHY mode: TSOP_0 is the bit
asserted for all 32 bits.
4 x 8 Single-PHY mode:
Each bit of
TSOP_0:3 corresponds to the respective
TDAT[3:0]_n channel.

Transmit End-of-Packet.
TEOP indicates the end of a packet and is
valid when asserted simultaneously with
TENB.
32-bit Multi-PHY mode: TEOP_0 is the bit
asserted for all 32 bits.
4 x 8 Single-PHY mode: Each bit of
TEOP_0:3 corresponds to the respective
TDAT[3:0]_n channel.
