RS8973
Single-Chip SDSL/HDSL Transceiver
A 2-byte read/write register that stores the countdown interval for Startup Timer 3 in unsigned binary format.
Each increment represents 1024 symbol periods. The contents of this register are automatically loaded into its
associated timer after the timer_restart bit is set, or after the timer counts down to zero while in the continuous
mode.
A 2-byte read/write register that stores the countdown interval for Startup Timer 4 in unsigned binary format.
Each increment represents 1024 symbol periods. The contents of this register are automatically loaded into its
associated timer after the timer’s timer_restart bit is set, or after it counts down to zero while in the continuous
mode.
A 2-byte read/write register that stores the countdown interval for the Meter Timer in unsigned binary format.
Each increment represents one symbol period. The contents of this register are automatically loaded into its
associated timer after the timer’s timer_restart bit is set, or after it counts down to zero while in the continuous
mode.
A 2-byte read/write register that stores the countdown interval for the SNR Alarm Timer in unsigned binary
format. Each increment represents one symbol period. The contents of this register are automatically loaded into
its associated timer after the timer’s timer_restart bit is set, or after it counts down to zero while in the
continuous mode.
A 2-byte read/write register that stores the countdown interval for General Purpose Timer 3 in unsigned binary
format. Each increment represents one symbol period. The contents of this register are automatically loaded into
its associated timer after the timer’s timer_restart bit is set, or after it counts down to zero while in the
continuous mode.
A 2-byte read/write register that stores the countdown interval for General Purpose Timer 4 in unsigned binary
format. Each increment represents one symbol period. The contents of this register are automatically loaded into
its associated timer after the timer’s timer_restart bit is set, or after it counts down to zero while in the
continuous mode.
