DS3161/DS3162/DS3163/DS3164
Bit 2: Transmit System Fill Level Inversion (TFLVI) – When 0, the polarity of the TPXA, TDXA, and TSPA
signals will be normal (high for data available). When 1, the polarity of the TPXA, TDXA, and TSPA signals will be
inverted (low for data available).
Bit 1: Transmit System Interface Byte Reordering Enable (TSBRE) – When 0, byte reordering is disabled, and
the first byte transmitted is transferred across the system interface as the most significant byte (TDATA[31:24] in
32-bit mode or TDATA[15:8] in 16-bit mode). When 1, byte reordering is enabled, and the first byte transmitted is
transferred across the system interface as the least significant byte (TDATA[7:0]).
Bit 0: Transmit System HEC Transfer (THECT) – When 0, The HEC byte is not transferred across the transmit
system interface. When 1, the HEC byte is transferred across the transmit system interface with the cell data.

Bit 0: Transmit System Interface Parity Error Interrupt Enable (TPREIE) – This bit enables an interrupt if the
TPREL bit in the TSISRL register is set and the bit in
GL.ISRIE.PSRIE[4:1] that corresponds to this port is set.
0 = interrupt disabled
1 = interrupt enabled
