Timing of Control Register
AKM mode
AKM mode is the data in I/F with 3-wire serial control, these data are included by Op-code (3bit), Address
(LSB-first, 5bit) and Control data (LSB-first, 8bit). A side of transmitted data is output to each bit by “
↓
” of
CCLK, a side of receiving data is input by “
↑
” of CCLK. Writing of data becomes effective by “
↑
” of CSN. CSN
should be held to “H” at no access.
Address except 00H
～
04H inhibits control of writing. And CCLK always need 16 edges of “
↑
” during CSN =
“L”.

SSB mode
SSB mode is the data in I/F with 2-wire serial interface, these data are included by information bit (3bit) and data
bit (LSB-first, 8bit). Serial clock (SCK) is burst-transmitted, not continuous receiving data. Transmitter outputs
each bit by “
↑
” of SCK, receiver latches the bit when transmitting the data is input by “
↓
” of SCK. Writing of data
and command becomes effective by next “
↑
” of SCK after taking in the last data bit (D7).
Address except 00H
