Oct 01, 2010
The transfer clock frequency for 3-wire serial I/O (CSI00, CSI01, CSI10, CSI20, CSI40, CSI41) communication can be
(1) Master
(2) Slave
The operation clock (f
(Transfer clock frequency) = {Operation clock (f
(Transfer clock frequency) = {Frequency of serial clock (SCK) supplied by master}
Note The permissible maximum transfer clock frequency is f
Remark The value of SDRmn[15:9] is the value of bits 15 to 9 of serial data register mn (SDRmn) (0000000B to
1111111B) and therefore is 0 to 127.
