Cautions 1. The N-ch open-drain output voltage is the normal voltage, not the medium voltage.
(e) Port function register 4 (PF4)
(f) Pull-up resistor option register 4 (PU4)
This 8-bit register specifies normal output or N-ch open-drain output.
It can be read or written in 8-bit or 1-bit units.
This is an 8-bit register that specifies connection of an internal pull-up resistor.
This register can be read or written in 8-bit or 1-bit units.
2. PF4n = 1 is enabled only in the following cases. Otherwise, the setting is prohibited.
3. Be sure to set N-ch open-drain output when using I
4. Follow the procedure below to set N-ch open drain.
After reset:
After reset:
n = 1: SO0, SDA
n = 2: SCK0, SCL
<1> Set the P4n bit to 1.
<2> Set the PF4n bit to 1.
<3> Set the CSIE0 bit of the CSIM0 register or the IICE bit of the IICC register to 1.
<4> Set the PFC4n bit.
<5> Set the PMC4n bit to 1.
