About Power mode transitions

Hello,Community

There are two questions about Table 6-8 Power mode transitions in i.MX 7 Dual Applications Processor Reference Manual.

(1) Does this mean that timer interrupt is enabled by LP Time Alarm Enable in SNVS_LP Control Register (LPCR)?
Which field should I check to see if an interrupt was asserted?

(2) If DP_EN of SNVS_LP Control Register (LPCR), can PMIC_ON_REQ signal be set to 0 in TOP?

Table 6-8. Is the Configuration with internal PMIC column of Power mode transitions Dumb PMIC?
