This register allows the µP to access to internal SIGX registers addressed by the
A[5:0] bits and perform the operation specified by the R/WB bit. Writing to this
register with a valid address and R/WB bit initiates an internal µP access request
cycle.The R/WB bit selects the operation to be performed on the addressed
register: when R/WB is set to a logic 1, a read from the internal SIGX register is
requested, when R/WB is set to a logic 0, an write to the internal SIGX register is
requested.
