1. HS stands for high sink capability.
Table 12. Legend/abbreviation for the pin description table
Type I= input, O = output, S = power supply
Level
Input CM = CMOS (standard for all I/Os)
Output HS = high sink (8 mA)
Output speed
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
Port and control
configuration
Input float = floating, wpu = weak pull-up
Output T = true open drain, OD = open drain, PP = push pull
Reset state
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).
