17.11.2 LCD Frame Counter Control register (LCD_FCC)
Address Offset: 0x04
The frame counter (FC) will start to count up from 0x0 when FCENB = 1, and add 1 when a frame is updated. When the
counter value reaches FCT[5:0], FC will reset as 0x0 by HW, the LCD frame interrupt flag will become 1. If LCD frame
interrupt is enabled (FCIE =1), the LCD frame interrupt is generated and sent to the interrupt controller.
