bit has no effect. The processor leaves debug mode after the TAP
controller update-DR state is entered.
When the EX bit is set, the processor leaves debug mode and
resumes normal operation until another debug request is generated.
The exit command is executed only if the GO bit is set and the
operation is a read/write to the CPUSCR or a read/write to “no register
selected.” Otherwise, the EX bit has no effect. The processor exits
debug mode after the TAP controller update-DR state is entered.
The RS field defines the source for the read operation or the
destination for the write operation.
