8.4
Duration of the Bit Check
If no transmitter signal is present during the bit check, the output of the ASK/FSK demodulator
delivers random signals. The bit check is a statistical process and T
Bit-check varies for each check.
Therefore, an average value for T
Bit-check is given in the electrical characteristics. TBit-check
depends on the selected baud-rate range and on T
Clk. A higher baud-rate range causes a lower
value for T
Bit-check resulting in a lower current consumption in polling mode.
In the presence of a valid transmitter signal, T
Bit-check is dependent on the frequency of that sig-
nal, f
Sig, and the count of the checked bits, NBit-check. A higher value for NBit-check thereby results in
a longer period for T
Bit-check requiring a higher value for the transmitter pre-burst TPreburst.
8.5
Receiving Mode
If the bit check was successful for all bits specified by N
Bit-check, the receiver switches to receiving
mode. According to Figure 8-2 on page 13, the internal data signal is switched to pin DATA in
that case, and the data clock is available after the start bit has been detected (see Figure 9-1 on
page 20). A connected microcontroller can be woken up by the negative edge at pin DATA or by
the data clock at pin DATA_CLK. The receiver stays in that condition until it is switched back to
polling mode explicitly.
