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
0x010 4 bits[31:0]: 0x10001
0x014 4 bits[31:16]: ((HSW + HBP) * clocks_per_pixel) >> 1, bits[15:0]: (((HSW + HBP + hact) * clocks_per_pixel) >> 1) + 1
0x01C 4 bits[28:16]: VSW + VBP - 1, bits[12:0]: ((vtotal + 1) >> 1) - VFP
0x020 4 bits[28:16]: VSW + VBP + ((vtotal - 1) >> 1), bits[12:0]: vtotal - VFP + 1
0x024 4 bits[31:16]: (HSW * clocks_per_pixel) >> 1, bit[0]: 1
0x02C 4 bits[31:0]: 0x10001
0x030 4 bits[28:16]: VSW, bits[15:0]: (htotal * clocks_per_pixel) >> 1
0x034 4 bits[28:16]: (vtotal + 1) >> 1, bits[15:0]: ((htotal * clocks_per_pixel) >> 2) + 1
0x038 4 bits[28:16]: VSW + ((vtotal + 1) >> 1), bits[15:0]: (htotal * clocks_per_pixel) >> 2
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)
