ADDRC Number of cycles in address phase; can be
multiplied by CMULT.
CMDDELAY Number of programmed command delay cycles;
can be multiplied by CMULT.
WAITRDC Number of programmed wait states for read
accesses; always multiplied by CMULT.
BURSTC Number of data cycles; can be multiplied by
CMULT.
RDRECOVC Number of minimum recovery cycles after a read
access; can be multiplied by CMULT.
DTACS Number of minimum recovery cycles when the next
access points to a different memory region; always
multiplied by CMULT.
