Setting Example of Display Control Clock in RGB Interface Operation

Register

The display operation via DPI is performed in synchronization with the internal clock (PCLKD) that is generated by dividing PCLK frequency.

PCDIVH[3:0]: When PCLKD is High, the number of clocks is set in unit of 1 clock.

PCDIVL[3:0]: When PCLKD is Low, the number of clocks is set in unit of 1 clock.

PCDIVH and PCDIVL (division ratio setting registers) should be set so that the difference between PCLKD frequency and the internal oscillation clock (678kHz) is minimized.

Set PCDIVL to PCDIVH or PCDIVH − 1.

Make sure (number of PCLK frequency) ≥ (number of RTN clocks) ∗ (division ratio of DIV) ∗ (PCDIVH +

PCDIVL)

Setting example (frame frequency: 60Hz)

Internal clock: Internal oscillation clock = 678kHz 1/1 Div. = (DIVE[2:0] = 2’b0) HFP = 10 clocks

FP = 8’h8, BP = 8’h8, NL = 6B (432 lines)

Æ59.35Hz

PCLK: Hsync = 10 clocks

HBP = 20 clocks

HFP = 10 clocks

60Hz ⋅ (8+432+8) lines (10+20+240+10) clocks = 7.53MHz PCLK frequency = 7.53MHz

7.53MHz/678kHz = 11.11 (Set PCDIVH and PCDIVL so that PCLK frequency is divided into 11.)

7.53/11 = 685kHz

685kHz / 25 clocks / 448 lines = 61.2Hz

PCDIVH = 4’h6

PCDIVL = 4’h5
