: Only MB90485B series
OUT0 to OUT5
P00 to P07 (8 pins) : with an input pull-up resistance setting register.
P10 to P17 (8 pins) : with an input pull-up resistance setting register.
P40 to P47 (8 pins) : with an open drain setting register.
P70 to P77 (8 pins) : with an open drain setting register.
MB90485B series only
I2C pin P77 and P76 are N-ch open drain pin (without P-ch) . However, MB90V485B uses
the N-ch open drain pin (with P-ch) .
P20 to P27, P30 to P37, P40 to P47 and P70 to P77 are also used as 3 V/5 V I/F pin.
As for MB90V485B, input pins (PWC0, PWC1, PWC2/EXTC/SCL and SDA pins) for PWC/
PG/I2C become CMOS input.
Note : In the above diagram, I/O ports share internal function blocks and pins. However, when a
set of pins is used with an internal module, it cannot also be used as an I/O port.
