Chapter 12: LPC24XX LCD controller
7.11 Masked Interrupt Status register (LCD_INTSTAT, RW - 0xFFE1 0024)
The LCD_INTSTAT register is Read-Only, and contains a bit-by-bit logical AND of the
LCD_INTRAW register and the LCD_INTMASK register. A logical OR of all interrupts is
provided to the system interrupt controller.
The contents of LCD_INTSTAT register are described in Table 12–270
.
7.12 Interrupt Clear register (LCD_INTCLR, RW - 0xFFE1 0028)
The LCD_INTCLR register is Write-Only. Writing a logic 1 to the relevant bit clears the
corresponding interrupt.
The contents of the LCD_INTCLR register are described in Table 12–271
.
