11.7.5 Calculating transfer rate
register 02 (SMR02).
464
The transfer rate for simplified I
The operation clock (MCK) is determined by serial clock select register 0 (SPS0) and bit 15 (CKS02) of serial mode
(Transfer rate) = {Operation clock (MCK) frequency of target channel} ÷ (SDR02[15:9] + 1) ÷ 2
Remark The value of SDR02[15:9] is the value of bits 15 to 9 of the SDR02 register (0000001B to
Caution Setting SDR02[15:9] = 0000000B is prohibited. Setting SDR02[15:9] = 0000001B or more.
