FSDAT [7:0]
fs counter data output
• _{FSDAT [7:0] is the fs calculation counter value. The data length is 8 bits, FSDAT0 is LSB, and FSDAT7 is MSB.}
• _{The relation between the count value and fs is expressed by the following equation.}
fs = 6144/FSDAT (kHz)
• _{Since fs is calculated with 6.144MHz-clock, the calculation accuracy is subject to this clock.}
• _{The calculation counter value is 8-bit output, so the fs capable of calculating is 24kHz or higher.}
12.3.4 Read register 3 (readout of first 48 bits of channel status)
• _{The first 48 bits of channel status can be read with the demodulation function.}
• _{The readout channel status data is output with LSB first.}
• _{For readout, set the CCB address to 0xEC.}
• _{The channel status data cannot be updated after the CCB address is set.}
• _{The relation between the read registers and the channel status data is shown below.}
