Registers

Offset Size Description
0x004 4 bits[1:0]: Video mode (0 = Progressive, 0b11 = Interlaced)
0x00C 4 bits[28:16]: vtotal, bits[12:0]: (vtotal + 1) >> 1
0x014 4 bits[31:16]: ((HSW + HBP) * clocks_per_pixel) >> 1, bits[15:0]: (((HSW + HBP + hact) * clocks_per_pixel) >> 1) + 1
0x030 4 bits[31:16] = VSW
0x050 4 Interrupts ack/clear (read = triggered interrupts, write = clear interrupt)
0x054 4 Interrupt enable mask (bit 1 = some interrupt)
0x410 4 DSI Command read FIFO status (bit 5 = Read FIFO empty)
0x430 4 DSI Command read FIFO
0x500 4 DSI Command FIFO
0x510 4 Another command FIFO (used to write the packet for command reads)
0x838 4 DSI auto clock configuration (1 = only HS clock, 0 = auto gate when data in LP)
