3.7.3
BAUD RATE SELECT BITS (BRS)
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:
BAUDRATE SELECT
3.7.4
MINIMUM FOUR TRANSMISSIONS
(MTX4)
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
TRANSMIT PULSE ENABLE (TXEN)
If this bit is cleared, no transmission pulse is transmit-
ted before a transmission. If the bit is set, a START
pulse (1 T
E
long) is transmitted after button de-bounc-
ing, before the preamble of the first code word.
3.7.6
S3 SETTING (S3SET)
This bit determines the value of S3 in the function code
during a transmission and the high trip point selected
by V
LOWS
in section 3.6.2. If this bit is cleared, S3 mir-
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
EXTENDED SERIAL NUMBER
(XSER)
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).
