Unless marked, all flags must be cleared by the application software.
Note 1: Cleared automatically by hardware when the service routine is entered.
Note 2: If edge-triggered, the flag is cleared automatically by hardware when the service routine is entered. If level-triggered, the flag follows the
state of the interrupt pin.
Note 3: The global 1-Wire interrupt-enable bit (EOWMI) and individual 1-Wire interrupt source enables are located in the internal 1-Wire bus
master interrupt enable register, and must be accessed through the OWMAD and OWMDR SFRs. Individual 1-Wire interrupt source
flag bits that are located in the internal 1-Wire bus master Interrupt flag register are accessed in the same way.
One’s Complement Adder
The DS80C410 implements a one’s complement adder to support the Internet checksum algorithm. The adder
contains a 16-bit accumulator and is accessed through the one’s complement adder data (OCAD) SFR.
Writing two bytes to the OCAD register initiates a summation between the 16-bit accumulator and the 16-bit value
entered. When entering a new 16-bit value for summation, the MSB should be loaded first and the LSB loaded
second. The calculation begins on the first machine cycle following the second write to the OCAD register and
executes in a single machine cycle. This allows back-to-back writes of 16-bit data to the OCAD register for
summation. The carry out bit from the high-order bit of the calculation is added back into the low-order bit of the
accumulator.
Reading two bytes from the OCAD register downloads the contents of the 16-bit accumulator. When reading the
16-bit accumulator through the OCAD register, the MSB is unloaded first and the LSB is unloaded second. The 16-
bit accumulator is cleared to 0000h following the second read of the OCAD SFR.
The following is an example sequence for producing an Internet checksum for transmission.
Read OCAD twice to make certain that the 16-bit accumulator = 0000h
Write MSB of 16-bit value to OCAD
Write LSB of 16-bit value to OCAD
