7. PROCESSOR INTERFACE
The DS26504 is controlled via a nonmultiplexed (BIS[1:0] = 01) or a multiplexed (BIS[1:0] = 00)
parallel bus. There is also a serial bus mode option, as well as a hardware mode of operation. The bus
interface type is selected by BIS1 and BIS0 as shown in Table 7-1.

Hardware Mode
7.1 Parallel Port Functional Description
In parallel mode, the DS26504 can operate with either Intel or Motorola bus timing configurations. If the
BTS pin is tied low, Intel timing will be selected; if tied high, Motorola timing will be selected. All
Motorola bus signals are listed in parentheses (). See the timing diagrams in the AC Electrical
Characteristics section for more details.
7.2 SPI Serial Port Interface Functional Description
A serial SPI bus interface is selected when the bus select is 10 (BIS[1:0] = 10). In this mode, a
master/slave relationship is enabled on the serial port with three signal lines (SCK, MOSI, and MISO)
and a chip select (
CS), with the DS26504 acting as the slave. Port read/write timing is not related to the
system read/write timing, thus allowing asynchronous, half-duplex operation. See the AC Electrical
Characteristics section for the AC timing characteristics of the serial port.
7.2.1 Clock Phase and Polarity
Clock Phase and Polarity are selected by the CPHA and CPOL pins. The slave device should always be
configured to match the bus master. See the SPI Serial Port Mode section for detailed functional timing
diagrams.
7.2.2 Bit Order
The most significant bit (MSB) of each byte is transmitted first.
7.2.3 Control Byte
The bus master will transmit two control bytes following a chip select to a slave device. The MSB will be
a R/
W bit (1 = read, 0 = write). The next 6 bits will be padded with zeros. The LSB of the first byte will
be A[7]. The second control byte will be the address bits (A[6:0]) of the target register, followed by a
Burst bit in the LSB position (1 = Burst, 0 = Nonburst).
7.2.4 Burst Mode
The last bit of the second control byte (LSB) is the Burst Mode bit. When the Burst bit is enabled (set to
1) and a read operation is performed, the register address is automatically incremented after the LSB of
the previous byte read to the next register address. Data will be available on the next clock edge following
the LSB of the previous byte read. When the Burst bit is enabled (set to 1) and a write operation is
performed, the register address will be automatically incremented to the next byte boundary following the
LSB of the previous register write, and 8 more data bits will be expected on the serial bus. Burst accesses
