SRIX4K operation
All commands, data and CRC are transmitted to the SRIX4K as 10-bit characters using ASK
modulation. The start bit of the 10 bits, b
SRIX4K at the antenna is demodulated by the 10% ASK demodulator, and decoded by the
internal logic. Prior to any operation, the SRIX4K must have been selected by a Select
command. Each frame transmitted to the SRIX4K must start with a start of frame, followed
by one or more data characters, two CRC bytes and the final end of frame. When an invalid
frame is decoded by the SRIX4K (wrong command or CRC error), the memory does not
return any error code.
When a valid frame is received, the SRIX4K may have to return data to the reader. In this
case, data is returned using BPSK encoding, in the form of 10-bit characters framed by an
SOF and an EOF. The transfer is ended by the SRIX4K sending the 2 CRC bytes and the
EOF.
