MCS0ACCVAL1[3:0]:

These bits define the access time for MCS0. If ENMCS0PAGE is set, these bits will be used for

the first access and MCS0ACCVAL2[3:0] will be used for the next three accesses for reads only.

For writes, only these bits are used. If ENMCS0PAGE is not set, these bits and

MCS0ACCVAL2[3:0] should be set with the same value. If ENMCS0PAGE is set, these bits must

be set to at least $1.

MCS0ACCVAL2[3:0]:

These bits define the access time for the next three reads in a burst sequence if ENMCS0PAGE

is set. If ENMCS0PAGE is not set, these bits and MCS0ACCVAL1[3:0] should be set with the

same value. If ENMCS0PAGE is set, these bits must be set to at least $2.

CS3ACCVAL1[3:0]:

These bits define the access time for CS3. If ENCS3PAGE is set, these bits will be used for the

first access and CS3ACCVAL2[3:0] will be used for the next three accesses for reads only. For

writes, only these bits are used. If ENCS3PAGE is not set, these bits and CS3ACCVAL2[3:0]

should be set with the same value. If ENCS3PAGE is set, these bits must be set to at least $1.

CS3ACCVAL2[3:0]:

These bits define the access time for the next three reads in a burst sequence if ENCS3PAGE is

set. If ENCS3PAGE is not set, these bits and CS3ACCVAL1[3:0] should be set with the same

value. If ENCS3PAGE is set, these bits must be set to at least $2.

CS2ACCVAL1[3:0]:

These bits define the access time for CS2. If ENCS2PAGE is set, these bits will be used for the

first access and CS2ACCVAL2[3:0] will be used for the next three accesses for reads only. For

writes, only these bits are used. If ENCS2PAGE is not set, these bits and CS2ACCVAL2[3:0]

should be set with the same value. If ENCS2PAGE is set, these bits must be set to at least $1.

CS2ACCVAL2[3:0]:

set. If ENCS2PAGE is not set, these bits and CS2ACCVAL1[3:0] should be set with the same

value. If ENCS2PAGE is set, these bits must be set to at least $2.
