20.2.6 Supported Resolution

20.2.6.1 MCU I/F
Parameters for maximum image size calculation：

Max. dot clock: MAX_DOT_CLK = system_clock/4 = 100MHz/4 = 25MHz

Refresh frequency: F = 30 (F/S)
For 16-bit I/F mode:
max_image_size = MAX_DOT_CLK/F = 912*912
For 8-bit I/F mode:
max_image_size = MAX_DOT_CLK/(F*2) = 645*645
20.2.6.2 RGB I/F
Parameters for maximum image size calculation：

Max. dot clock: MAX_DOT_CLK = system_clock/4 = 100MHz/4 = 25MHz

Refresh frequency: F = 60 (F/S)
