System Configuration
6.4.19 Hsync/Vsync Period Difference Interrupt Control Register (HV_PD_INTR) —FF00:12 (FF12)
This register defines the Hsync/Vsync period difference interrupt control. When the current pixel counts for a
Hsync period or the current Hsync line counts for a Vsync period are different from the previous counts, it will
trigger the interrupt, if this register is enabled.

6.4.20 Hsync Line Count Difference Value Register (HL_DIFF) —FF00:13 (FF13)
This register defines the Hsync line count difference value. When the difference between the previous Hsync
line count in vertical total and the current count is greater than this register or overflow, it will generate the
interrupt to the MCU.
