expressions.
register 0n (SMR0n).
416
The transfer clock frequency for 3-wire serial I/O (CSI00, CSI10) communication can be calculated by the following
(1) Master
(2) Slave
The operation clock (MCK) is determined by serial clock select register 0 (SPS0) and bit 15 (CKS0n) of serial mode
Remarks 1. The value of SDR0n[15:9] is the value of bits 15 to 9 of the SDR0n register (0000000B to
(Transfer clock frequency) = {Operation clock (MCK) frequency of target channel} ÷ (SDR0n[15:9] + 1) ÷ 2 [Hz]
(Transfer clock frequency) = {Frequency of serial clock (SCK) supplied by master}
Note The permissible maximum transfer clock frequency is f
