RSLIP Buffer Delay—Difference between RX and RSB timebase in time slot intervals.
Reported once per frame coincident with RFRAME interrupt [ISR3; addr 008]. Actual delay
may vary significantly, depending on which time slots are assigned.
Active RSB Slip Buffer Half—This bit indicates which half of the receive slip buffer is
currently supplying data to the Receive System Bus (0 = RLIP_LO, 1 = RSLIP_HI). The
processor can write data to the opposite buffer half.
Active Receiver Slip Buffer Half—This bit indicates which half of the receive slip buffer is
currently receiving data from the receiver (0 = RSLIP_LO, 1 = RSLIP_HI). The processor can
read data from the opposite buffer half.
TSLIP Buffer Delay—Difference between TSB and TX timebase in time slot intervals.
Reported once per frame coincident with TFRAME interrupt [ISR3; addr 008]. The actual
delay may vary significantly, depending on which time slots are assigned.
Active Transmitter Slip Buffer Half—This bit indicates which half of the transmit slip buffer is
currently supplying data to the transmitter (0 = TSLIP_LO, 1 = TSLIP_HI). The processor can
write data to the opposite buffer half.
Active TSB Slip Buffer Half—This bit indicates which half of the transmit slip buffer is
currently receiving data from the Transmit System Bus (0 = TSLIP_LO, 1 = TSLIP_HI). The
processor can read data from the opposite buffer half.
000000 = RX to RSB delay in the range of 0–7 bits
111111 = RX to RSB delay in the range of 504–511 bits
000000 = TSB to TX delay in the range of 0–7 bits
111111 = TSB to TX delay in the range of 496–503 bits
