Note: 1. data write operation from the microcontroller is performed irrespective of the setting of D[1:0] bits.
2. The D[1:0] setting is valid on both 1st and 2nd displays.
3. The non-lit display level from the source output pins is determined by instruction (PTS).
CL When CL = “1”, the 8-color display mode is selected.

BASEE
Base image display enable bit. When BASEE = “0”, no base image is displayed. The ILI9325 drives
liquid crystal at non-lit display level or displays only partial images. When BASEE = “1”, the base
image is displayed. The D[1:0] setting has higher priority over the BASEE setting.
PTDE[1:0]
Partial image 2 and Partial image 1 enable bits
PTDE1/0 = 0: turns off partial image. Only base image is displayed.
PTDE1/0 = 1: turns on partial image. Set the base image display enable bit to 0 (BASEE = 0).

FP[3:0]/BP[3:0]
The FP[3:0] and BP[3:0] bits specify the line number of front and back porch periods respectively.
When setting the FP[3:0] and BP[3:0] value, the following conditions shall be met:
BP + FP ≤ 16 lines
FP ≥ 2 lines
BP ≥ 2 lines
