• P22C0-P20C0, P22C1-P20C1 (bits 3-0)
Initial value
Initial value
To directly drive LEDs, select N-channel open drain output mode.
The P22C0 to P20C0 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.
