MTV512M
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.
