Ready output. A high output indicates that the
target device is ready to accept another data
byte. A low output indicates that the target
device is busy and not ready to receive another
data byte.
In PPA configuration schemes, this pin drives
out high after power-up, before configuration
and after configuration before entering user-
mode. In non-PPA schemes, it functions as a
user I/O during configuration, which means it is
tri-stated.
