MCS3ACCVAL1[3:0]:

These bits define the access time for MCS3. If ENMCS3PAGE is set, these bits will be used for

the first access and MCS3ACCVAL2[3:0] will be used for the next three accesses for reads only.

For writes, only these bits are used. If ENMCS3PAGE is not set, these bits and

MCS3ACCVAL2[3:0] should be set with the same value. If ENMCS3PAGE is set, these bits must

be set to at least $1.

MCS3ACCVAL2[3:0]:

These bits define the access time for the next three reads in a burst sequence if ENMCS3PAGE

is set. If ENMCS3PAGE is not set, these bits and MCS3ACCVAL1[3:0] should be set with the

same value. If ENMCS3PAGE is set, these bits must be set to at least $2.

MCS2ACCVAL1[3:0]:

These bits define the access time for MCS2. If ENMCS2PAGE is set, these bits will be used for

the first access and MCS2ACCVAL2[3:0] will be used for the next three accesses for reads only.

For writes, only these bits are used. If ENMCS2PAGE is not set, these bits and

MCS2ACCVAL2[3:0] should be set with the same value. If ENMCS2PAGE is set, these bits must

be set to at least $1.

MCS2ACCVAL2[3:0]:

These bits define the access time for the next three reads in a burst sequence if ENMCS2PAGE

is set. If ENMCS2PAGE is not set, these bits and MCS2ACCVAL1[3:0] should be set with the

same value. If ENMCS2PAGE is set, these bits must be set to at least $2.

MCS1ACCVAL1[3:0]:

These bits define the access time for MCS1. If ENMCS1PAGE is set, these bits will be used for

the first access and MCS1ACCVAL2[3:0] will be used for the next three accesses for reads only.

For writes, only these bits are used. If ENMCS1PAGE is not set, these bits and

MCS1ACCVAL2[3:0] should be set with the same value. If ENMCS1PAGE is set, these bits must

be set to at least $1.

MCS1ACCVAL2[3:0]:

These bits define the access time for the next three reads in a burst sequence if ENMCS1PAGE

is set. If ENMCS1PAGE is not set, these bits and MCS1ACCVAL1[3:0] should be set with the

same value. If ENMCS1PAGE is set, these bits must be set to at least $2.
