4.4.3.8.1.9 SOTCB – Start
Of Telegram Conditions for Path B
| Name: | SOTCB |
| Offset: | 0x093 |
| Reset: | 0x00 |
This is
the configuration register for the wake check OK on path B interrupt (RDSIFR.WCOB) and
start of telegram on path B interrupt (RDSIFR.SOTB). A condition is activated by setting
the corresponding bit to high. The interrupts are set if all activated conditions are
met. The current status of the conditions can be seen in the SOTSB
register.

Bit 7 – WCOAOE Wake Check OK from
Path A OK Enable
Writing this bit to
‘1’ selects the wake check OK on path A condition (RDSIFR.WCOA)
as a precondition for a successful wake check OK on path B (RDSIFR.WCOB) and start
of telegram on path B (RDSIFR.SOTB).
Bit 6 – RROEB RSSI Range OK
Enable for Path B
Writing this bit to
‘1’ enables the RSSI range OK on path B (SOTSB.RROB) as a
condition for the wake check OK on path B (RDSIFR.WCOB) and start of telegram on
path B (RDSIFR.SOTB) interrupts. The SOTSB.RROB is ignored if this bit is
cleared.
Bit 5 – SFIDEB Start of Frame
Identifier Match Enabled for Path B
Writing this bit to
‘1’ enables the start frame ID match on path B as a condition
for the start of telegram on path B (RDSIFR.SOTB). The start frame ID result is
ignored if this bit is cleared.
Bit 4 – WUPEB Wake-Up Pattern
Match Enabled for Path B
Writing this bit to
‘1’ enables the wake-up pattern match on path B as a condition
for the wake check OK on path B (RDSIFR.WCOB) and start of telegram on path B
(RDSIFR.SOTB) interrupts. The wake-up pattern result is ignored if this bit is
cleared.
Bit 3 – MANOEB Manchester Coding
OK Enabled for Path B
Writing this bit to
‘1’ enables the Manchester coding check OK output from path B
as a condition for the wake check OK on path B (RDSIFR.WCOB) and start of telegram
on path B (RDSIFR.SOTB) interrupts. The Manchester coding check result is ignored if
this bit is cleared.
Bit 2 – SYTOEB Symbol Timing OK
Enabled for Path B
Writing this bit to
‘1’ enables the symbol timing check OK output from path B as a
condition for the wake check OK on path B (RDSIFR.WCOB) and start of telegram on
path B (RDSIFR.SOTB) interrupts. The symbol timing check result is ignored if this
bit is cleared.
Bit 1 – AMPOEB Amplitude OK
Enabled for Path B
Writing this bit to
‘1’ enables the demodulator amplitude check OK output from path
B as a condition for the wake check OK on path B (RDSIFR.WCOB) and start of telegram
on path B (RDSIFR.SOTB) interrupts. The demodulator amplitude check result is
ignored if this bit is cleared.
Bit 0 – CAROEB Carrier Check OK
Enabled for Path B
Writing this bit to
‘1’ enables the carrier check OK output from path B as a
condition for the wake check OK on path B (RDSIFR.WCOB) and start of telegram on
path B (RDSIFR.SOTB) interrupts. The carrier check result is ignored if this bit is
cleared.
