Preliminary

VSYNC Interrupt

The MTV512M checks the VSYNC input pulse and generates an interrupt at its leading edge. The VSYNC flag

is set each time when MTV512M detects a VSYNC pulse. The flag is cleared by S/W writing a “0”.

INTFLG F48h(r/w)

INTEN F49h(w)

Vsync

EVsync

INTFLG(w): Interrupt flag. An interrupt event will set its individual flag, and, if the corresponding interrupt enable

bit is set, the INT1 source of 8051 core will be driven by a zero level. Software MUST clear this

register while serving the interrupt routine.

Vsync = 1 → No action.

= 0 → Clears VSYNC interrupt flag.

INTFLG(r): Interrupt flag.

Vsync = 1 → Indicates a VSYNC interrupt.

INTEN(w): Interrupt enable.

EVsync = 1 → Enables VSYNC interrupt.
