This address range allows write-only access to the pattern RAM. It is used to load monochrome patterns into the pattern
cache with automatic color expansion. Each bit in this address range represents one pixel in the pattern cache. A ‘1’ written
here is converted to the foreground color and written to the Pattern RAM. A ‘0’ written here is converted to the background
color and written to the Pattern RAM.
A monochrome pattern always consists of 64 bits of data regardless of the pixel color depth. The amount of color expanded
data, however, is dependent on color depth. The monochrome data should be written to the address range 0x1600 -
0x1607.
Note that patterns must be loaded sequentially because the lower order address bits are ignored as a pattern is loaded.

Description
Powerdown register for the module
0 = Normal operation of the peripheral. This is the reset value.
1 = Module is powered down and module clock can be removed.
At powerdown, module responds to all reads with DEADABBA
(except for reads of powerdown bit) and all writes with ERR ACK
(except for writes to powerdown bit).
Ignore during writes and read as zeroes.
