(b) Use as 2.5V or 3 V output port
Notes 1. In the 78K0R/IB3, UART0 cannot be used to communicate between devices with different power
<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 POMn register to 1 to set the N-ch open drain output (V
<5> Set the output mode by manipulating the PMn register.
<6> Operation is done only in the low level according to the operating status of the serial array unit.
Remark
<1> After reset release, the port mode is the input mode (Hi-Z).
<2> Externally pull up 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 register to 1 to set the N-ch open drain output (V
<5> Set the corresponding bit of the PM3 register to the output mode (data I/O is possible in the output
