Table 5: Legend/abbreviations for pinout tables
Type I= Input, O = Output, S = Power supply
Level
Input CM = CMOS
Output HS = High sink
Output speed
O1 = Slow (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 internal reset release).
Unless otherwise specified, the pin state is the same during the reset
phase and after the internal reset release.

Figure 3: LQFP 48-pin pinout
1. (HS) high sink capability.
2. (T) True open drain (P-buffer and protection diode to V
DD
not implemented).
3. [ ] alternate function remapping option (If the same alternate function is shown twice, it
indicates an exclusive choice not a duplication of the function).
