Ground (0 V).
Open-Drain PWM (Pulse Width Modulation) D/A Converter 0. The
output pulse width is programmable by writing data to Reg10 with
8-bit resolution to control the pulse width duration from 0 to 255/256.
The output frequency is 31.25KHz (or15.625KHz). In applications, the
external pull-up resistor can be connected to 12V for the desired full-
scale output.
Open-Drain PWM D/A Converter 1. See DA0. The output pulse
width is programmable by Reg11.
Open-Drain PWM D/A Converter 2. See DA0. The output pulse
width is programmable by Reg12.
Horizontal Blank. The pulse width and the delay of HBLANK vs.HS
input leading edges are programmable by Reg7 and Reg6,
respectively.
Vertical Blank. The output pulse width is programmable by Reg9.
Crystal 1. Used to interface to the oscillator. An 8MHz(or 4MHz)
crystal must be connected between this pin and pin X2. An appropriate
capacitor to Ground, whose value depends on the specified C L of the
crystal, must be connected. This pin can also be used as a direct input
when the external oscillator is used.
