7.6.5.4LCD DMA Frame ID Registers (FIDRx)

FIDRx, shown in Table 7-9, correspond to DMA channels 0 and 1 and contain an ID field that describes the current frame. The particular use of this field is up to the user. This ID register is copied to the LCD Controller Interrupt ID Register when an interrupt occurs.

These read-only registers are loaded indirectly via the frame descriptors, as described in Section 7.6.5.1.

These are read-only registers. Ignore reads from reserved bits.
