The same with DF_RD. ( Read Only)
Internal Pre Interrupt.
Internal interrupt @ TX/RX byte count = (INTR_CNT * 16).
If want to disable the internal pre-interrupt, please set INTR_CNT = 0
While internal pre-interrupt occurred, the interrupt status TX_OK/RX_OK will be both
zero. The RD_FLAG will indicate the pre-interrupt is TX or RX.
EX:INTR_CNT [3:0] = 0x01 → internal interrupt @ TX/RX = byte 16.
