TxFIFOStatMask
Title:
Transmit data FIFO Status interrupt Mask register
Address:
$0x23
Function:
RW
Description:
Masks interrupts in the TxFIFOStatus register. On taking N_RESET Low, these bits are set
active, so masking out all possible interrupt sources. Each inactive bit will allow its associated
status bit to generate an interrupt. In the case of the status bits marked in the TxFIFOStatus
register with a parenthesised ‘L’, taking the mask bit inactive will enable the latching
mechanism.
