* 8 pulses of fc/32 (also 18.88us)
*
* The mode FPGA_HF_SIMULATOR_MODULATE_424K_8BIT which we use to simulate tag,
* works like this.
* - A 1-bit input to the FPGA becomes 8 pulses on 423.5kHz (fc/32) (18.88us).
* - A 0-bit inptu to the FPGA becomes an unmodulated time of 18.88us
*
* In this mode the SOF can be written as 00011101 = 0x1D
* The EOF can be written as 10111000 = 0xb8
* A logic 1 is 01
