4. P52/ExSCK1/SCL0, P97/SDA0, P86/SCK1/SCL1, P42/SDA1, and port G are NMOS
push-pull outputs.
When the SCL0, SDA0, SCL1, SDA1 (ICE = 1), ExSDAA, ExSCLA, ExSDAB, or
ExSCLB pin is used as an output, it is NMOS open-drain output. Therefore, an external
pull-up resistor must be connected in order to output high level.
P52/ExSCK1, P97, P86/SCK1, P42 (ICE = 0), and port G high levels are driven by
NMOS.
An external pull-up resistor is necessary to provide high-level output from ExSCK1 and
SCK1.
