NAME AND DESCRIPTION
RAM Interrupt Enable Bit. Setting this bit allows the data pump to interrupt
the host when a RAM read/write request has been completed.
Receive Data Interrupt Enable Bit, Parallel Data Mode Only. This bit, when
set, causes the data pump to generate an interrupt whenever the RXI bit is
set.
Transmit Data Interrupt Enable Bit, Parallel Data Mode Only. This bit,
when set, causes the data pump to generate an interrupt whenever the TXI
bit is set.
