The value written to this field is added to the semaphore count in an atomic way such that simultaneous
software adds and DMA hardware substracts happening on the same clock are protected. This bit field reads
back a value of 0x00. Writing a value of 0x02 increments the semaphore count by two, unless the DMA
channel decrements the count on the same clock, then the count is incremented by a net one.
