10.2.1 BP[3:0] — Analog Backplane Pins
This output signal vector represents the analog backplane waveforms of the LCD32F4BV1 module and is
connected directly to the corresponding pads.
10.2.2 FP[31:0] — Analog Frontplane Pins
This output signal vector represents the analog frontplane waveforms of the LCD32F4BV1 module and is
connected directly to the corresponding pads.
10.2.3 VLCD — LCD Supply Voltage Pin
Positive supply voltage for the LCD waveform generation.
10.3 Memory Map and Register Definition
This section provides a detailed description of all memory and registers.
10.3.1 Module Memory Map
The memory map for the LCD32F4BV1 module is given in Table 10-2. The address listed for each register
is the address offset. The total address for each register is the sum of the base address for the
LCD32F4BV1 module and the address offset for each register.
