Transmit Signaling Register 1 to 12
The transmit signaling register access is enabled by setting bit FMR5.EIBR = 1. Each
register contains the bit robbing information for 8 DS0 channels. With the transmit CAS
empty interrupt ISR1.CASE the contents of these registers is copied into a shadow
register. The contents is subsequently sent out in the corresponding bit positions of the
next outgoing multiframe. XS1.7 is sent out first in channel 1 frame 1 and XS12.0 is sent
out last. The transmit CAS empty interrupt ISR1.CASE requests that these registers

These bits are only valid if FMR1.ECM is cleared. They have to be set
before reading the error counters. They are reset automatically if the
corresponding error counter high byte has been read. With the rising
edge of these bits the error counters are latched and then cleared.
