Bit 0/Unused, must be set = 0 for proper operation.
Bit 1/Transmit Open Circuit Detect Condition (TOCD). Set when the device detects that the TTIP and TRING outputs are
open-circuited. Note: This function not supported in transmit 6312kHz mode.
Bit 2/Transmit Current Limit Exceeded Condition (TCLE). Set when the 50mA (rms) current limiter is activated whether
the current limiter is enabled or not. Note: This function not supported in transmit CMI, 64kHz or 6312kHz mode.
Bit 3/Unused, must be set = 0 for proper operation.
Bit 4/Jitter Attenuator Limit Trip Event (JALT). Set when the jitter attenuator FIFO reaches to within 4 bits of its useful
limit. Will be cleared when read. Useful for debugging jitter-attenuation operation. Note: The jitter attenuator is only available
in T1 and E1 modes.
Bit 5/Unused, must be set = 0 for proper operation.
Bit 6/Unused, must be set = 0 for proper operation.
Bit 7/Unused, must be set = 0 for proper operation.
