PAL: BS = 33 (21H); default after reset if
strapping pin 13 tied to HIGH
NTSC: BS = 25 (19H); default after reset if
strapping pin 13 tied to LOW
default after reset
a HIGH impulse resets synchronization of the
encoder (first field, first line)
PAL: BE = 29 (1DH); default after reset if
strapping pin 13 tied to HIGH
NTSC: BE = 29 (1DH); default after reset if
strapping pin 13 tied to LOW
