Section 22
22.3.6
The result of counting 1 cycle of ringing waveform with AFE_FS is shown here.
22.3.7
ACDR is the register to store the AFE control word. After 1 is written to HC bit (ACTR1), data is
transferred to AFE at the timing of 3rd FS.
22.3.8
ASDR is the register to store the AFE status word. After 1 is written to HC bit (ACTR2), data is
transferred to ASDR from AFE at the timing of 3rd FS.
