14.7.5 Calculating transfer rate
register mn (SMRmn).

Jul 2, 2010
The transfer rate for simplified I
The operation clock (MCK) is determined by serial clock select register m (SPSm) and bit 15 (CKSmn) of serial mode
(Transfer rate) = {Operation clock (MCK) frequency of target channel} ÷ (SDRmn[15:9] + 1) ÷ 2
Caution Setting SDRmn [15:9] = 0000000B is prohibited. Set SDRmn[15:9] to 0000001B or greater.
Remarks 1. The value of SDRmn[15:9] is the value of bits 15 to 9 of the SDRmn register (0000000B to
