to the bit or by Bus RESET. Under normal operation the host should
clear the PAV bit after PPRIM is read.

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.
