Datasheet

a. Program the LCDLIDDCTL register along with the chip select configuration register,
LIDDCSnCFG.
b. Select the DMA parameters in the LCDDMACTL register. Program the frame buffer
boundaries in the LCDDMABAFB0 and LCDDMACAFB0 registers.
c. Enable any required interrupts in the LCDIM register.
d. Initiate LIDD mode transactions by setting the DMAEN bit in the LCDLIDDCTL register.
5. When operating in Raster Mode:
a. Program the LCDRASTRCTL register along with the raster timings in the LCDRASTRTIMn
registers.
b. Configure the subpanel display in the LCDRASTRSUBPn registers.
c. Select the DMA parameters such as burst size, and memory layout in the LCDDMACTL
register. Program the frame buffer boundaries in the LCDDMABAFBn and LCDDMACAFBn
registers.
d. Enable any required interrupts in the LCDIM register.
e. Initiate Raster mode transactions by setting the LCDEN bit in the LCDRASTRCTL register.
The LCD DMA may interface to internal SRAM or the external memory through EPI for transfer of
data. To configure the EPI for use with LCD, refer to “External Peripheral Interface (EPI)” on page 846.
Note: When using the LCD with EPI to interface to external memory, the external code address
space 0x1000.0000 must be selected by programing the ECADR field to 0x1 in the EPI
Address Map (EPIADDRMAP) register at EPI offset 0x01C.
26.7 Register Map
Table 26-9 on page 1868 lists the LCD registers. The offset listed is a hexadecimal increment to the
register's address, relative to the LCD module's base address of 0x4405.0000.
