ATM Transmitter/Receiver with UTOPIA Interface
0x30—EN_CELL_INT (Enable Cell Interrupts)
The EN_CELL_INT register (0x30) enables interrupts for the CELL_STATUS register (0x3B). Setting a bit in
EN_CELL_INT enables each interrupt condition to appear on STAT_INT (pin 64).
0x32—TX_K1K2 (Transmit K1 and K2 Value)
The TX_K1K2 register (0x32) contains the APS Transmit K1 and K2 values.
0x33—RX_K1K2 (Receive K1 and K2 value)
The RS_K1K2 register (0x33) contains the APS Receive K1 and K2 values.
