LCD driver clock
When the source clock is the main clock (fpll)
1/2¹⁸, 1/2¹⁷, 1/2¹⁶, 1/2¹⁵, 1/2¹⁴, 1/2¹³, 1/2¹², 1/2¹¹
When the source clock is the sub clock (fslow)

LCD power supply
LCD power supply is separated from V_DD5 (can be used when V_LC1 ≤ V_DD5)
External power supply voltage can be selected. (Supply voltage is supplied from V_LC1 , V_LC2 , and V_LC3 pins)
Internal dividing resistors
External power supply voltage is divided the voltage input to V_LC1 by internal resistors.
