Product data sheet
PUBLIC
As long as the internal signal accept further data is logic 1, data can be written to the FIFO
buffer. The MFRC500 appends this data to the data stream transmitted using the RF
interface.
If the internal accept further data signal is logic 0, the transmission terminates. All data
written to the FIFO buffer after the accept further data signal was set to logic 0 is not
transmitted, however, it remains in the FIFO buffer.
Remark: If parity generation is enabled (ParityEn = logic 1), the parity bit is the last bit
transmitted. This delays the accept further data signal by a duration of one bit.
If the TxLastBits[2:0] bits are not zero, the last byte is not transmitted completely. Only the
number of bits set by TxLastBits[2:0], starting with the least significant bit are transmitted.
This means that the internal state machine has to check the FIFO buffer status at an
earlier point in time; see
Since in this example TxLastBits[2:0] = 4, transmission stops after bit 3 is transmitted and
the frame is completed with an EOF, if configured.
