Clearing status latched registers on a read or write access is selectable via the GL.CR1.LSBCRE register bit.
Clearing on read clears all bits in the register, while the clear on write clears only those bits which are written with a
‘1’ when the user writes to the status latched register.
To use the Clear on Read method, the user must only read the status latched register. All bits are set to zero after
