*1 : 3 V/5 V I/F pin : All pins should be for 3 V power supply without P20 to P27, P30 to P37, P40 to P47, and
P70 to P77.
*2 : P76/P77 pins are N-ch open drain pins (without P-ch) at built-in I
2
C. However, MB90V485B uses the N-ch open
drain pin (with P-ch) .
*3 : It is setting of Jumper switch (TOOL VCC) when emulator (MB2147-01) is used.
Please refer to the MB2147-01 or MB2147-20 hardware manual (3.3 Emulator-dedicated Power Supply
Switching) about details.
Notes :
As for MB90V485B, input pins (PWC0, PWC1, PWC2/EXTC/SCL and SDA pins) for PWC/
