Transmit data
Nothing is assigned.
In an attempt to write to these bits, write 0 . The value, if read, turns out to be 0 .
SUM
Assuming that set value = n, BRGi divides the count source by
n + 1
Nothing is assigned.
In an attempt to write to these bits, write 0 . The value, if read, turns out to be indeterminate.
