Panel Interface Control 1 (R010h)
RTNI[4:0]: Sets 1H (line) period. This setting is valid when the R61509V’s display operation is
synchronized with internal clock signal.

Note: In Power Supply Instruction Setting, Deep Standby Exit Sequence and Sleep Mode Exit Sequence,
RTNI bit must be set at the “Initial instruction setting” state. See “Power Supply Setting Sequence”
and “Instruction Setting Sequence and Refresh Sequence”.
DIVI[1:0]: Sets the division ratio of the internal clock frequency. The R61509V’s internal operation is
synchronized with the frequency divided internal clock, which is set according to the division ratio
determined by DIVI[1:0] setting. The frame frequency can be changed by setting RTNI and DIVI bits.
When changing the number of lines to drive the LCD panel, adjust the frame frequency too. For details,
see Frame-Frequency Adjustment Function.
In RGB interface operation, the DIVI[1:0] setting has no effect.
