Note1: When is setting (PF0, PF1, PF2, PF3)=(1, 1, 0, 1) and (X, X, 1, 1), the frame frequency is same as frame
frequency at the time of the (PF0, PF1, PF2, PF3)=(1, 0, 1, 0) setting (fosc/896, fCK1/896).
Note2: In the case of the LC75890E(QIP44M), the output pins are effective for only P1 to P11 pins.
