Product specification
Microcontrollers for PAL/SECAM TV
with OSD and VST
P8xCx66 family
For example, if the contents of VSTL = 000 0000, no
additional pulses are generated; if the contents of
VSTL = 111 1111, the number of additional pulses that are
generated is 127. Therefore, up to 127 additional pulses
can be added during a T
std
period. Additional pulses must
be distributed equally in one T
std
period (pulse distribution
procedure).
Figure 25 shows some examples of OUT2.

OUTPUT
If the contents of VSTH = 001 1101, and the contents of
VSTL = 000 0010, then the TPWM output is as shown in
Fig.26. The additional OUT2 pulses are generated in
subperiods 32 and 96.
Two extreme cases are worthy of further analysis:
VSTH = 000 0000, and VSTL = 000 0000. No coarse
pulses will be generated and OUT1 is LOW for the whole
T
std
period. No fine pulses will be generated and
consequently TPWM is LOW for the whole T
std
period.
VSTH = 111 1111 and VSTL = 111 1111. This value of
VSTH results in OUT1 being LOW for the first t
0
period
but will go HIGH for the remaining 127
×
t
0
periods in the
T
sub
cycle. This value of VSTL will generate
127 additional fine pulses (in every T
sub
cycle except in
T
sub0
). These additional fine pulses fill the gaps in the
OUT1 output (except in T
sub0
). Consequently, the
TPWM output will be LOW for the first t
0
period (T
sub0
)
but will be HIGH for the remainder of the T
std
period.
