Memory map and register definition
49.3.6 LCD backplane enable register (LCD_BPENn)
When PEN[n] = 1, the BPEN[63:0] bits configure the corresponding LCD pin to operate
as an LCD backplane or an LCD frontplane. Most applications set a maximum of eight of
these bits. Initialize these registers before enabling the LCD controller.
Addresses: LCD_BPENL is 400B_E000h base + 18h offset = 400B_E018h

The reset value of this register depends on the reset type:
LCD pin enable
The PEN[63:0] bits enable the LCD_P[63:0] pins for LCD operation. PENL contains PEN[31:0], and
PENH contains PEN[63:32].
Each LCD_P[63:0] pin can be configured as a backplane or a frontplane based on the corresponding
BPEN[n] bit in the backplane enable register (BPEN). If LCDEN = 0, these bits have no effect on the state
of the I/O pins. Set PEN[63:0] bits before LCDEN is set.

Backplane enable
The BPEN[63:0] bits configure the LCD_P[63:0] pins to operate as an LCD backplane or LCD frontplane.
BPENL contains BPEN[31:0], and BPENH contains BPEN[63:32].
If LCDEN = 0, these bits have no effect on the state of the I/O pins. It is recommended to set BPEN[63:0]
bits before LCDEN is set.
