Valid only in Out Of Service phase when JSS7E=1 (CSR2).

vious provider primitive. PLOST is cleared when PAV is cleared and
by a Bus RESET. Writing to this bit has no affect.
new provider primitive has been placed in PPRIM.
READ/CLEAR ONLY and is set by the chip and cleared by writing a ”1”
to the bit or by Bus RESET. Under normal operation the host should
clear the PAV bit after PPRIM is read.

tions.
Yellow Book definitions for SINs & SIEs (SF = 9 & 10 respectively).
This primitive will occur only if enabled by RYEL=1 in Protocol Options.
timer for TCLK has expired due to no transition on TCLK for more than
the number of SYSCLK cycles as selected by CSR4<15:14>.
timer for RCLK has expired due to no transition on RCLK for more than
the number of SYSCLK cycles as selected by CSR4<13:12>.
received within the previous 32xTP time (where TP is the poll timer).
This primitive is only issued if RSUTE=1 (CSR2<12>).
phase has occured, due to an alignment failure.
AERM is exceeded, timer T2 times out, or timer T3 times out.
phase has occured, due to a received LSSU.
phase has occured, due to a timer T1 time out.
Service phase has occured, due to a transmit link failure. The trans-
mit link will fail if timers T6 or T7 time out.
phase has occured due to receive link failure. A receive link failure will
occur when more than 2 out of 3 signal units have a FIB or BSN error.
phase has occured, due to SUERM being exceeded.

received since remote processor outage condition has been reported.
BSNT to the Status Buffer as requested by UPRIM 12.
The pointer to the retransmission buffer is available in STATUS buffer.
the remote node has entered into congestion.
PROVIDER PRIMITIVE LOST is set by MK50H27 when a provider
PROVIDER PRIMITIVE AVAILABLE is set by the MK50H27 when a
