Read Threshold Register
Read buffer data available to the event threshold as a number of bytes available. The device side must have the intelligence
to activate the interrupt either when this threshold is exceeded or when it sees it useful (end of packet).
15:0 VALUE16[15:0] The CPU writes to this field during initialization. The value written to this register is made available by
hardware in the PP_RD_THRESHOLD register. When AP writes to the PP_RD_THRESHOLD regis-
ter, this register is updated with the new value and the RD_THRESHOLD interrupt is provided.
