27.6.10 Masked Interrupt Status register
The INTSTAT register is Read-Only, and contains a bit-by-bit logical AND of the INTRAW
register and the INTMASK register. A logical OR of all interrupts is provided to the system
interrupt controller.
27.6.11 Interrupt Clear register
The INTCLR register is Write-Only. Writing a logic 1 to the relevant bit clears the
corresponding interrupt.
3
VCOMPRIS
Vertical compare raw interrupt status.
Set when one of the four vertical regions is reached, as selected
by the LcdVComp bits in the CTRL register.
Generates an interrupt if the VCompIM bit in the INTMSK
register is set.
0x0
4
BERRAW
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 INTMSK register is
set.
