Bits 3 to 0: Digit/segment pin function switch (DBR3 to DBR0)

Bits 3 to 0 designate the first digit pin and the first segment pin of those pins that can function

both ways. Bits DR3 to DR0 of the VFD digit control register (VFDR) and bits SR4 to SR0 of

VFSR must be set so that the first digit and segment pins are operational. Otherwise these pins

will not function.

FS7 to FS0

Notes: Digit pins (FD) and segment pins (FS) are controlled by both VFDR and VFSR. During a

key scan interval, digit pins (FD) and segment pins (FS) function as general-purpose ports.
