Bit 7: BDLAB. When this bit is set to a logical 1, designers can access the divisor (in 16-bit binary
Bit 6 - 5: Reserved. Always 0 when read.
Bit 4: EPE. This bit describes the number of logic 1's in the data word bits and parity bit only when bit
Bit 3: PBE. When this bit is set, the position between the last data bit and the stop bit of the SOUT will
Bit 2 – 0: Reserved. Bit 2 is always 0 and bit 1 – 0 are always 1 when read.
5.7
This register contains global interrupt enable bit of Smart Card interface.
Bit 7 - 4: Reserved. Always 0 when read.
Bit 3: The Smart Card interface interrupt output is enabled by setting this bit to a logic 1.
Bit 2 – 0: Reserved. Always 0 when read.
5.8
This 8-bit register provides information about the status of the data transfer during communication.
Bit 7: RFEI. This bit is set to a logic 1 when there is at least one parity bit error, no stop bit error or
format) from the divisor latches of the baudrate generator during a read or write operation.
When this bit is reset, the Receiver Buffer Register, the Transmitter Buffer Register, or the
Interrupt Control Register can be accessed.
3 is programmed. When this bit is set, an even number of logic 1's are sent or checked. When
the bit is reset, an odd number of logic 1's are sent or checked.
be stuffed with the parity bit at the transmitter. For the receiver, the parity bit in the same
position as the transmitter will be detected.
Interrupt Enable Register (IER, at "base address + 4")
Smart Card Status Register (SCSR, at "base address + 5")
silent byte detected in the FIFO. It is cleared by reading SCSR until there are no remaining
errors left in the FIFO.
