HEADER
When PWM mode is selected the header length (low
time between preamble and data bits start) can be set
to 10 x T
E
or 3 x T
E
. The 10 x T
E
mode is recommended
for compatibility with previous K

L
OQ
encoder mod-
els. In Manchester mode, the header length is fixed and
set to 4 x T
E
.
4.5.13
RFEN
RFEN
selects whether the
RFEN
output is enabled or
disabled. If enabled, S3 is only sampled 2 s after the
last button is released and at the start of the first trans-
mission. If disabled S3 functions the same as the other
S inputs. For typical implementation of the rfHCS362G/
362F the RFEN bit = 0.
4.6
SYNCHRONOUS MODE
In Synchronous mode, the code word can be clocked
out on DATA using S2 as a clock. To enter Synchro-
nous mode, S2 must be taken HIGH and then DATA
and S0 or S1 are taken HIGH. After Synchronous mode
is entered, DATA and S2 must be taken LOW. The data
is clocked out on DATA on every falling edge of S2.
Auto-shutoff timer is not disabled in Synchronous
mode. Refer to Figure 4-1 and Figure 4-2.
