The LCD Controller supports character-based LCD panels by ensuring the bus cycles for reading/writing commands and data are met. The LIDD (LCD Interface Display Driver) provides this support. The LIDD interfaces with an Arm CPU in the SoC using a VBUS slave port. Abundant programmable timing parameters can be configured such that the off-chip interface can support a wide variety of character based LCD panels. Alternatively, the DMA module can be used to mimic the CPU and perform a sequence of write-only data bus transactions to the character based LCD panel. The Motorola and Intel interfaces support asynchronous and synchronous modes. The only difference between the two is that, for synchronous mode, the internal bus clock is output on a pin that replaces CS1. In other words, only one character panel can be supported under synchronous mode while two panels can be supported for asynchronous mode.
