Jul 2, 2010
The transfer clock frequency for 3-wire serial I/O (CSI00, CSI01, CSI10, CSI20) communication can be calculated by
(1) Master
(2) Slave
The operation clock (MCK) is determined by serial clock select register m (SPSm) and bit 15 (CKSmn) of serial mode
(Transfer clock frequency) = {Operation clock (MCK) frequency of target channel} ÷ (SDRmn[15:9] + 1) ÷ 2 [Hz]
(Transfer clock frequency) = {Frequency of serial clock (SCK) supplied by master}
Note The permissible maximum frequency is the smaller of f
Remarks 1. The value of SDRmn[15:9] is the value of bits 15 to 9 of the SDRmn register (0000000B to
