3. HARDWARE MODE AND CPU BUS MODE
The DS315x can operate in either hardware mode or CPU bus mode. In hardware mode, pulling configuration input
pins high or low does all configuration, and all status information is reported on status output pins. Internal registers
are not accessible in hardware mode. The device is configured for hardware mode when the HW pin is wired high
(HW = 1).
In CPU bus mode, most of the configuration and status pins used in hardware mode are reassigned to be address,
data, and control lines that provide a glueless interface to an 8-bit microprocessor bus. Through the CPU bus, an
external processor can access a set of internal registers. Setting configuration register bits high or low can do
configuration, and status information can be read from status register bits. Events indicated by status register bits
can also activate the interrupt output pin (INT), if configured to do so by a set of interrupt-enable bits. A few
configuration and status pins are active in hardware mode and CPU bus mode to support specialized applications,
such as protection switching. The device is configured for CPU bus mode when the HW pin is wired low (HW = 0).
With the exception of the HW pin, configuration and status pins available in hardware mode have corresponding
register bits in the CPU bus mode. The hardware mode pins and the CPU bus mode register bits have identical
names and functions, with the exception that all register bits are active high. For example, LOS is indicated by the
receiver on the
RLOS pin (active low) in hardware mode and the RLOS register bit (active high) in CPU bus mode.
The few configuration input pins that are active in CPU bus mode also have corresponding register bits. In these
cases, the actual configuration is the logical OR of pin assertion and register bit assertion. For example, the
transmitter output driver is tri-stated if the
TTS pin is asserted (i.e., low) or the TTS register bit is asserted (high).
Figure 3-1 and Figure 3-2 show block diagrams of the DS315x in hardware mode and in CPU bus mode. Table 4-A
lists the pins that are active in each mode.
