3.7.3
BRS selects the speed of transmission and the code
word blanking. Table 3-5 shows how the bit is used to
select the different baud rates and Section 5.5 provides
detailed explanation in code word blanking.
TABLE 3-5:
3.7.4
If this bit is cleared, only one code is completed if the
HCS201 is activated. If this bit is set, at least four com-
plete code words are transmitted, even if code word
blanking is enabled.
3.7.5
If this bit is cleared, no transmission pulse is transmit-
ted before a transmission. If the bit is set, a START
pulse (1 T
ing, before the preamble of the first code word.
3.7.6
This bit determines the value of S3 in the function code
during a transmission and the high trip point selected
by V
rors S2 during a transmission. If the S3SET bit is set,
S3 in the function code (Button Status) is always set,
independent of the value of S2.
3.7.7
If this bit is set, a long 32-bit Serial Number is transmit-
ted. If this bit is cleared, a standard 28-bit Serial Number
is transmitted followed by 4 bits of the function code
(Button Status).
