FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
RUN COMMAND
The Run command gives access to all operating modes:
Normal, Polling, and Polling + INT Timer. It allows
selection
of t
WAIT
and t
WAKE
, and configures the programmable input
blocks. Bit 7 is currently unused. Note that the Run register
values are unknown after exiting the Sleep mode.
MOD[2:1] OPERATING MODE
In the Run command, the two MOD bits place the device
in one of three operating modes: Normal, Polling, and Polling
+ INT Timer.
ST[3:1] – OFF TIME BETWEEN SAMPLES (T
WAIT
)
During both Polling modes (with and without INT Timer
wake up, MOD2=[1]), these bits select the interval of time
(t
WAIT
) the Input Blocks are turned OFF; switch transitions
are not detected during the OFF interval.
WT[2:1] – WAKE UP TIME
These bits allow the device to assert an external interrupt
(INT) at the following intervals during Polling mode (MOD2 =
MOD1 = 1).
