Functional Description
39.7.4 Extended Space Operation
In either time, baseband or FSK mode, the space period can be made longer than the
maximum possible value of the space period register . Setting MSC[EXSPC] bit will
force the modulator to treat the next modulation period (beginning with the next load of
the counter and space period register) as a space period equal in length to the mark and
space counts combined . Subsequent modulation periods will consist entirely of these
extended space periods with no mark periods . Clearing MSC[EXSPC] will return the
modulator to standard operation at the beginning of the next modulation period .
39.7.4.1 EXSPC Operation in Time Mode
To calculate the length of an extended space in time or baseband mode, add the mark and
space times and multiply by the number of modulation periods when MSC[EXSPC] is
set.
