Remarks 1. p: CSI number (p = 00, 01, 11, 20), m: Unit number (m = 0, 1), n: Channel number (n = 0, 1, 3)
2. f
MCK: Serial array unit operation clock frequency
(Operation clock to be set by the serial clock select register m (SPSm) and the CKSmn bit of serial
mode register mn (SMRmn). m: Unit number (m = 0,1), n: Channel number (n = 0, 1, 3))
