During T
Sleep
and T
Startup
the receiver is not sensitive to a transmitter signal. To guaran-
tee the reception of a transmitted command the transmitter must start the telegram with
an adequate preburst. The required length of the preburst depends on the polling
parameters T
Sleep
, T
Startup
, T
Bit-check
and the start-up time of a connected microcontroller
(T
Start,μC
). Thus, T
Bit-check
depends on the actual bit rate and the number of bits (N
Bit-check
)
to be tested.
The following formula indicates how to calculate the preburst length.

Sleep Mode
The length of period T
Sleep
is defined by the 5-bit word Sleep of the OPMODE register,
the extension factor XSleep (according to Table 9),
and the basic clock cycle T
Clk
. It is
calculated to be:
T
Sleep
= Sleep X
Sleep
1024 T
Clk
In US- and European applications, the maximum value of T
Sleep
is about 60 ms if XSleep
is set to 1. The time resolution is about 2 ms in that case. The sleep time can be
extended to almost half a second by setting XSleep to 8. XSleep can be set to 8 by bit
XSleep
Std
to 1.
According to Table 8, the highest register value of sleep sets the receiver into a perma-
nent sleep condition. The receiver remains in that condition until another value for Sleep
is programmed into the OPMODE register. This function is desirable where several
devices share a single data line and may also be used for microcontroller polling — via
Pin POLLING/_ON, the receiver can be switched on and off.
