

Duty drive (SEG0 to SEG31) and static drive (ST0 to ST8)

can be switched.



Each of COM0 to COM3, SEG0 to SEG31, V0, V1, V2, and

V3 pins for duty drive can be switched to the

general-purpose port. (The SEG23 to SEG31 pins can be

switched to static driving.)



V0, V1, V2 and V3 pin can be used as the general-purpose

port. But V3 pin cannot be used as an output pin.



Each of ST0 to ST8 pins for static drive can be switched to

the general-purpose port, or it can be switched to the

segment output of duty drive.



MB91F575/7: The amplitude of the SEG0 to SEG22 output

is determined by the VCC5 power supply pin or by the V3

pin even if VCCE pin is supplied to 3.3V.


