Reserved.
BUSL
[1] rls-crw-i3
Buffer Underrun Status Latch = “1” indicates the transmit TDM Port ran out of
data. The S132 internal transmit processes were not able to keep up with the
transmit rate for this TDM Port.
COFASL
[0] rls-crw-i3
Change Of Frame Alignment Status Latch = “1” indicates a change of frame or
multi-frame timing error was detected (only valid for SFS = 1).

BUIE
[1] rwc-_-i3
Buffer Underrun Interrupt Enable. The combination of PTSRL.BUSL = 1 and
BUIE = 1 forces G.GSR1.PS = 1.
COFAIE
