FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
watchdog circuitry. If WDTO bit is logic [1], the watchdog has
timed out and the device is in Fail-Safe mode. IF WDTO is
logic [0], the device is in Normal mode (assuming the device
is powered and not in the Sleep mode), with the watchdog
either enabled or disabled.
PREVIOUS ADDRESS SOA4 : SOA0 = 00110
The returned data OD3 and OD2 contain the state of the
outputs HS2 and HS0, respectively, in case of Fail-Safe
state. This information is stated with the external resistance
placed at the FSI pin. OD1 indicates if the watchdog is
enabled or not. OD0 returns the state of the WAKE pin.
PREVIOUS ADDRESS SOA4 : SOA0 = 01110
The returned data OD3 : OD0 reflects the state of the direct
pins IN3 : IN0, respectively.
PREVIOUS ADDRESS SOA4 : SOA0 = 01111
The returned data OD3 -OD2 reports the overtemperature
bits configuration of the outputs [3, 2] set through the WDR
SPI register.
