45.12.24 Dithering Pattern DP6_7 Register
Name: DP6_7
Address:0x00500838
Access: Read-write
Reset value: 0xF5FFAFF
• DP6_7: Pattern value for 6/7 duty cycle
45.12.25 Power Control Register
Name: PWRCON
Address:0x0050083C
Access: Read-write
Reset value: 0x0000000e
• LCD_PWR: LCD module power control
0 = lcd_pwr signal is low, other lcd_* signals are low.
0->1 = lcd_* signals activated, lcd_pwr is set high with the delay of GUARD_TIME frame periods.
1 = lcd_pwr signal is high, other lcd_* signals are active.
1->0 = lcd_pwr signal is low, other lcd_* signals are active, but are set low after GUARD_TIME frame periods.
• GUARD_TIME
Delay in frame periods between applying control signals to the LCD module and setting LCD_PWR high, and between set-
ting LCD_PWR low and removing control signals from LCD module
• LCD_BUSY
Read-only field. If 1, it indicates that the LCD is busy (active and displaying data, in power on sequence or in power off
sequence).
