When ports 3 and 7 operate with V
Regarding inputs, normal input (CMOS)/TTL switching is possible on a bit-by-bit basis by port input mode registers 3
Moreover, regarding outputs, different power potentials can be supported by switching the output buffer to the N-ch
(a) Use as 2.5V or 3 V input port
(b) Use as 2.5V or 3 V output port
<1> After reset release, the port mode is the input mode (Hi-Z).
<2> If pull-up is needed, externally pull up the pin to be used (on-chip pull-up resistor cannot be used).
<3> Set the corresponding bit of the PIM3 and PIM7 registers to 1 to switch to the TTL input buffer.

<1> After reset release, the port mode changes to the input mode (Hi-Z).
<2> Pull up externally the pin to be used (on-chip pull-up resistor cannot be used).
<3> Set the output latch of the corresponding port to 1.
<4> Set the corresponding bit of the POM3 and POM7 registers to 1 to set the N-ch open drain output (V
<5> Set the output mode by manipulating the PM3 and PM7 registers.
<6> Communication is started by setting the serial array unit.
