Switching the Receiver Back
to Sleep Mode
The receiver can be set back to polling mode via Pin DATA or via Pin POLLING/_ON.
When using Pin DATA, this pin must be pulled to Low for the period t1 by the connected
microcontroller. Figure 19 illustrates the timing of the OFF command (see also Figure
34). The minimum value of t1 depends on BR_Range. The maximum value for t1 is not
limited but it is recommended not to exceed the specified value to prevent erasing the
reset marker. Note also that an internal reset for the OPMODE and the LIMIT register
will be generated if t1 exceeds the specified values. This item is explained in more detail
in the section “Configuration of the Receiver”. Setting the receiver to sleep mode via
DATA is achieved by programming bit 1 to be “1” during the register configuration. Only
one sync pulse (t3) is issued.
The duration of the OFF command is determined by the sum of t1, t2 and t10. After the
OFF command the sleep time T
Sleep
elapses. Note that the capacitive load at Pin DATA
is limited (see section “Data Interface”).
