The
Vertical sync control byte
includes the following bits:
- SSC:
Sandcastle without VBL
0: output SCP with VBL component
1: output SCP without VBL component
- NI:
Non interlace
0: interlace depends on source
1: no interlace
The
PWM control byte
includes the following bits:
- PWMS1..
PWMS0: PWM select
x0: same duty cycle in each line selected (adjustable by PWMC)
01: positive V-parabola after external integration available (amplitude
adjustable by PWMC)
11: negative V-parabola after external integration available (amplitude
adjustable by PWMC)
- PWMC5..
PWMC0: PWM control
These bits control either the duty cycle or the parabola amplitude
depending on PWMS0 according to the following table (if PWMS0 = 0
also PWMS1 defines the the duty cycle):
1)
V
OH
: PWM output High level, V
OL
: PWM output Low level
The PWM output may be used as switching output when PWMS0 = 0. If PWMC = 100000
and PWMS1 = 0 the output is Low. If PWMC = 011111 the output is continously High.
