Part Number:MSP430F6726
Hi community member,
Please let me confirm the following a question for LCD Controller with MSP430F6726.
In the data sheet (p.70 LCD_C Recommended Operating Conditions),
LCD frame frequency range (fFrame) is specified as follows:
The frequency of the LCD module (fLCD) is calculated from CONDITIONS.
(Min)fLCD = 2 x 4 x 0
= 0
(Max)fLCD = 2 x 4 x 100
= 800
Therefore, I understand that the recommended range of fLCD is 0 to 800 Hz.
So, I have a question about fLCD
[Question]
if it is set to a frequency outside the recommended range (>800Hz), What happens to the MCU ?
1) Does abnormal operation or malfunction occur?
Is the abnormal operation or malfunction temporary?
For example, if I temporarily set fLCD to a frequency out of the recommended range and then restore it or reset MCU, Is that a problem?
2) Is there a possibility of an abnormal voltage being generated on the LCD module?
Is there a possibility that the power supply voltage of the MCU will be exceeded when an abnormal voltage is generated?
3) The higher the fLCD, the higher the risk of 1), 2) occurring?
I would be most grateful if you show graphs, figures, data etc when raising LCD module frequency.
Thank you for your cooperation.
Best regards,
Cruijff
