LCDFRR – LCD Frame Rate Register
Table 23-3.
• Bit 7 – Res: Reserved Bit
This bit is reserved and will always read as zero.
• Bits 6:4 – LCDPS2:0: LCD Prescaler Select
The LCDPS2:0 bits selects tap point from a prescaler. The prescaled output can be further
divided by setting the clock divide bits (LCDCD2:0). The different selections are shown in
23-4. Together they determine the prescaled LCD clock (clk
module.
