For LPDDR2/3, DDR0 channel GROUP A can’t be exchanged in group, and each data in
it (DDR0_D0~D7) also cannot be exchanged with each other. DDR0 channel GROUP A
(DDR0_D0~D7) must match A or B channel (DDR0_D0~D7) in LPDDR2/3, meanwhile
DDR0_D0~D7 is one-to-one correspondence. Other GROUP (GROUP B, C, D) can be
exchanged in group. Moreover, each data in GROUP B/C/D (eg. DDR0_D8~D18) also
can be exchanged with each other. DDR1 channel GROUP (A, B, C, D) can be
exchanged in group. Moreover, each data in GROUP A/B/C/D (eg. DDR1_D0~D7) also
can be exchanged with each other, as shown in Fig 8-3.
