VSS1 = VSS2 = VSS3 = 0 V unless otherwise specified.
The A0, D0 to D5, D6 (SI), D7 (SCL), /RD (E), /WR (R/W), CSB, IMS, OSC, P/S, /DOF, RESB, and MODE terminals.
Used by internal analog circuits.
The A0, /RD (E), /WR, /(R/W), CSB, IMS, OSC, P/S, /DOF, RESB and MODE terminals.
Applies when the D0 to D5, D6 (SI), D7 (SCL) terminals are in a high impedance state.
These are the resistance values for when a specified voltage difference is applied between the output terminals
(SEGn/COMn) and the various power supply terminals (V0, XV0, VG & VM).
R
It indicates the current consumed by Bare Chip alone.
