(2) General-purpose
counter binary data
C19 to C0
Description
¤ I/O port; Data latching the state of pin 14 and other pins become I1 to I5. Latched when the
data output mode becomes effective.
Pin state=Hi: 1
=Low: 0
Currently, only pin 14 (SD state)
¤ Data latching the content of general-purpose counter (20-bit binary counter) becomes
C19 to C0.
C19 ← MSB of binary counter
C0 ← LSB of binary counter
