7.10 Raw Interrupt Status register (LCD_INTRAW, RW - 0xFFE1 0020)
Table 268. Interrupt Mask register (LCD_INTMSK, RW - 0xFFE1 001C)
The LCD_INTRAW register contains status flags for various LCD controller events. These
flags can generate an interrupts if enabled by mask bits in the LCD_INTMSK register.
The contents of LCD_INTRAW register are described in

Description
LCD next base address update interrupt enable.
0: The base address update interrupt is disabled.
1: Interrupt will be generated when the LCD base address
registers have been updated from the next address registers.
FIFO underflow interrupt enable.
0: The FIFO underflow interrupt is disabled.
1: Interrupt will be generated when the FIFO underflows.
Reserved, user software should not write ones to reserved bits.
The value read from a reserved bit is not defined.
Description
Reserved, user software should not write ones to reserved bits.
The value read from a reserved bit is not defined.
AHB master bus error raw interrupt status.
Set when the AHB master interface receives a bus error
response from a slave.
Generates an interrupt if the BERIM bit in the LCD_INTMSK
register is set.
Vertical compare raw interrupt status.
Set when one of the four vertical regions is reached, as selected
by the LcdVComp bits in the LCD_CTRL register.
Generates an interrupt if the VCompIM bit in the LCD_INTMSK
register is set.
LCD next address base update raw interrupt status.
Mode dependent. Set when the current base address registers
have been successfully updated by the next address registers.
Signifies that a new next address can be loaded if double
buffering is in use.
Generates an interrupt if the LNBUIM bit in the LCD_INTMSK
register is set.
FIFO underflow raw interrupt status.
Set when either the upper or lower DMA FIFOs have been read
accessed when empty causing an underflow condition to occur.
Generates an interrupt if the FUFIM bit in the LCD_INTMSK
register is set.
Reserved, user software should not write ones to reserved bits.
The value read from a reserved bit is not defined.
