P24C0, P22C0 to P20C0, P24C1, P22C1 to P20C1 (bits 4 and 2 to 0)
The P24C0, P22C0 to P20C0, P24C1, and P22C1 to P20C1 bits are used to select high-impedance output mode,
P-channel open drain output mode, N-channel open drain output mode, or CMOS output mode.
To directly drive LEDs, select N-channel open drain output mode.
