3.6 Interrupt Enable Control Registers
ATM Transmitter/Receiver with UTOPIA Interface
0x2F—EN_OVFL_INT (Enable Overflow Interrupts)
The EN_OVFL_INT register is located at address 0x2F and enables interrupts for the OVFL_STATUS register
(0x3A). Setting a bit in EN_OVFL_INT enables each interrupt condition to appear on STAT_INT.
