During recording, adjustment
for deviation of Y-FM
modulation.
During recording, adjustment
for carrier of Y-FM modulation.
During playback, chroma RF
signal input.
PB C LPF is built in, so that a
signal with the AFM and ATF
components (Y RF + C RF)
eliminated can be input.
RF SWP (switching pulse) and
HCHG (head change) pulse
input. Half H shift, HHS
cancel, ACC channel hold,
and PI/PS switching operate
at V

Input to BUS DECODER. CS
is used as chip select, and
data is latched at rising edge.
CK is the clock input. Use a
clock frequency fck of less
than 1.3MHz. SI is used as a
serial data input.
