I= input, O = output, S = power supply
Input
Output
O1 = Standard (up to 2 MHz)
O2 = Fast (up to 10 MHz)
O3 = Fast/slow programmability with slow as default state after reset
O4 = Fast/slow programmability with fast as default state after reset

Output
Bold X (pin state after reset release).
Unless otherwise specified, the pin state is the same during the reset phase (i.e.
“under reset”) and after internal reset release (i.e. at reset state).
