Function

POS-PHY Transmit Error Indicator

Active high signal used to indicate that the

current packet must be aborted. TERR

should only be considered valid when

TENB and TEOP are simultaneously

asserted.

TERR is sampled on the rising edge of

TFCLK.

POS-PHY Transmit Write Enable

Active low signal used to control the flow of

data to the transmit FIFOs.

When TENB is high, the TDAT[31:0],

TMOD, TSOP, TEOP, TPRTY and TERR

signals are invalid and are ignored by the

PM3386. However, the TSX signal if

asserted is valid and is processed by the

PM3386 only when TENB is high.

When TENB is low, the TDAT[31:0], TMOD,

TSOP, TEOP, TPRTY and TERR signals

are valid and are processed by the

PM3386. The TSX signal is ignored by the

PM3386 when TENB is low.

TENB is sampled on the rising edge of

TFCLK.

POS-PHY Transmit bus parity

The transmit parity (TPRTY) signal

indicates the parity calculated over the

TDAT bus. TPRTY is considered valid only

when TENB or TSX are asserted.

By default the PM3386 uses odd parity.

The PM3386 supports both even and odd

parity. The PM3386 reports any parity error

to the host processor via a maskable

interrupt, but does not interfere with the

transferred data.

TPRTY is sampled on the rising edge of

TFCLK.
