22.5.10 Interrupts
This section describes all interrupts originated by LCD64F6B.
22.5.10.1 EOF interrupt
LCDEN must be set to enable the interrupt at end of frame feature. Every time a frame generation was
completed a counter is decremented by 1. If the counter reaches zero End of Frame interrupt Flag (EOF)
bit is set and the counter is reset to NOF. The counter is reset to request interrupt at the end of every frame,
as if NOF would be 0x00, if LCDEN is asserted while the LCD is off.
The EOF flag can only be cleared by writing a 1. Writing a 0 has no effect. If enabled (LCDINT = 1), EOF
causes an interrupt request. The number of frames (NOF) bits determine how many frames are count until
EOF flag is set. The possible number of frames are:
Current

Plane switching
16 x boost
8 x boost
boost disabled
Standard current with
