Functional description
Before enabling the LCD controller by asserting the LCDEN bit in the GCR, configure
the LCD controller based on the end application requirements. Out of reset, the LCD
controller is configured with default settings, but these settings are not optimal for every
application. The LCD controller provides several versatile configuration settings and
options to support varied implementation requirements, including:
The LCD controller also provides an LCD pin enable control. Setting the LCD pin enable
bit in the PENn register for a particular LCD_Pn pin enables the LCD controller
functionality of that pin once the LCDEN bit is set. When the backplane enable bit in the
BPENn is set, the associated pin operates as a backplane. The WFyTOx registers can then
activate (display) the corresponding LCD segments on an LCD panel.
The WFyTOx registers control the on/off state for the segments controlled by the LCD
pins defined as front planes and the active phase for the backplanes. Blank display modes
do not use the data from the WFyTOx registers. When using the WFyTOx register for
frontplane operation, writing a 0 turns the segment off.
For pins enabled as backplane, the bits in WFn fields assign the phases of the backplane
(A-H) for the corresponding backplane pin. For a detailed description of LCD controller
operation for a basic seven-segment LCD display, see
description.
49.4.1 LCD controller driver description
The LCD controller driver has 8 modes of operation:
1488
• Frame frequency
• Duty cycle (number of backplanes)
• Backplane assignment (which LCD_P[63:0] pins operate as backplanes)
• Frame frequency interrupt enable
• Blinking frequency and options
• Power-supply configurations
• Fault detection configuration
• 1/1 duty (1 backplane) (Phase A), static mode
• 1/2 duty (2 backplanes) (Phase A, B), 1/3 bias (4 voltage levels)
• 1/3 duty (3 backplanes) (Phase A, B, C), 1/3 bias (4 voltage levels)
