isters, the value of single bits can be checked by using the SBIS and SBIC instructions.
all bits in the I/O register, writing a one back into any flag read as set, thus clearing the flag. The CBI and SBI instructions
work with registers 0x00 to 0x1F only.
ters as data space using LD and ST instructions, $20 must be added to these addresses. The AT90USB64/128 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 $60 - $1FF in SRAM, only the ST/STS/STD and LD/LDS/LDD instruc-
tions can be used.
