Note:
a) The max. frequency of the 1-phase input X0 (C243, C245, C246) and X2(C242) is
100kHz.
b) The max. frequency of the 1-phase 2-input (X0, X1) (C245, C246) and (X2, X3) (C249,
C250) is 100kHz.
c) The max. frequency of the 1-phase 2-input (X0, X1) (C247, C248) is 10kHz.
d) The max. frequency of the 2-phase 2-input (X0, X1) (C251, C252) and (X2, X3) (C253,
C254) is 5kHz.
e) 2-phase 2-input counting supports double and 4 times frequency, which is selected in
D1022 as the table in next page. Please refer to the below table for detailed counting
