18.4.10. PINC – The Port C Input Pins Address
When using the I/O specific commands IN and OUT, the I/O addresses 0x00 - 0x3F must be used. When
addressing I/O Registers as data space using LD and ST instructions, 0x20 must be added to these offset
addresses. The device is a complex microcontroller with more peripheral units than can be supported
within the 64 location reserved in Opcode for the IN and OUT instructions. For the Extended I/O space
from 0x60 in SRAM, only the ST/STS/STD and LD/LDS/LDD instructions can be used.
In ATmega103 compatibility mode, DDRC and PINC Registers are initialized to being Push-Pull Zero
Output. The port pins assumes their initial value, even if the clock is not running. Note that the DDRC and
PINC Registers are available in ATmega103 compatibility mode, and should not be used for 100% back-
ward compatibility.
