CHAPTER 10 I/O PORTS
Note:
SIL0, SIL1 are write-only, and “1” is always read from these bits. Therefore, instructions that perform a
read-modify-write (RMW) operation such as the INC/DEC instruction, cannot be used at DDRA.
●
DDRA: Bits 0 to 2, Bits 5 to 7 (unused bits)
"1" is always read from these bits. Writing to these bits is no effect.
