If RESETBMCU is required to be asserted first before any of the external regulators from

the corresponding group, the RESETBMCU_DLY provides a selectable delay to disable

the regulators after RESETBMCU is asserted.

If RESETBMCU_DLY is set to 0x00, all regulators in the same power down group as

RESETBMCU is disabled at the same time RESETBMCU is asserted.

Figure 11 shows an example of the power down sequence when PWRDWN_MODE = 1.
