Register 0x1012: TUL3 Interrupt Status/Enable 2
TXOPI:
UNPROVI:
TXOPE:
UNPROVE:
The start or end of packet interrupt is set high when either TSOP or TEOP is not asserted
with the first or last word of a POS-PHY packet, respectively. The TXOPI register bit is
cleared immediately after it is read, thus acknowledging the event has been recorded.
The POS-PHY Level3 unprovisioned address interrupt is set high when the value of
TDAT[7:0] addresses a non-existent channel buffer during in-band addressing.
interrupt is asserted when this value is greater than 0x0F. The UNPROVI register bit is
cleared immediately after it is read, thus acknowledging the event has been recorded.
UNPROVI interrupt does not remain asserted even when there is a persistent in-band
addressing error. A read of the UNPROVI will clear the interrupt. Hence, continuous in-
band addressing error results in only one interrupt.
The start or end of packet interrupt enable controls the assertion of the INTB output when
TXOPI is high. When TXOPE is set high, an interrupt is generated upon assertion event of
the TXOPI register. When TXOPE is set low, changes in the TXOPI status do not generate
an interrupt.
The unprovisioned address interrupt enable controls the assertion of the INTB output when
UNPROVI is high. When UNPROVE is set high, an interrupt is generated upon assertion
event of the UNPROVI register. When UNPROVE is set low, changes in the UNPROVI
status do not generate an interrupt.
