Legend:
x = undefined, R/W = Read/Write, Ro = Read-only Bit(s) in the register, Wo = Write-only Bit(s)
in the register.
Notes:
1. The contents of the I/O port DR registers are readable only in output configuration. In input configura-
tion, the values of the I/O pins are returned instead of the DR register contents.
2. The bits associated with unavailable pins must always be kept at their reset value.
3. Do not use single-bit instructions (SET, RES...) on Port Data Registers if any pin of the port is configured
in input mode (refer to
4. Depending on device. See device summary on page 1.
