Notes: 1. Since the DO pin is an n-channel open-drain output, the transition times (t_DC, t_DH) will differ with the value of
the pull-up resistor used.
2. The CE, CL, DI, and DO pins can be connected to the corresponding pins on other ICs that use the CCB
interface. (However, we recommend connecting the DO and CE pins separately if the number of available
microcontroller ports allows it.)
3. Serial data I/O becomes possible after the crystal oscillator starts oscillation.
