Our customer has several problems with hardware design:
a. If the customer's power supply is clear, Could use only one bead for (AVDD_1V8, DVDD_1V8, A2VDD_1V8, V1P8, PVDD_1V8) all 1.8V input?
b. about other I/O functions, can these pins keep the NC, pull-up or pull-down if I don't need to use them?
(eg DRx2, DRx3, CEC .....)
c. Is the external 12MHz crystal required if CEC_CLK is not used?
(If used by default, must the external 12MHz oscillator be used?
d. Do we have PCB files can provide to our customers?
