LCD Controller
18.4 REGISTER MODEL
18.4.1 LCD Controller Configuration Register
The 32-bit, memory mapped, read/write LCD controller configuration register (LCCR) holds
the mode and configuration parameters that you can use to operate your LCD panel.
BNUM—Number of Bursts
This field contains the number of burst cycles required for one refresh cycle.
EIEN—Exception Interrupt Enable
IEN—Interrupt Enable
IRQL—Interrupt Request Level
This field contains the priority request level of the LCD controller’s interrupt that is sent to
the system interface unit. Refer to Section 12.3.3 Programming the Interrupt Controller
for more information. This will generate an interrupt request level with a vector in the SIVEC
register if enabled with the SIMASK register. Both EOF and the exception interrupts use the
same request level.
