Table 2. Hardware Register Map
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 Section 7 "I/O PORTS" on page 37 for more details)
4. Depending on device. See device summary on page 1.
