Do the following steps to enter LPMx.5:
BIC #GIE, SR
MOV.B #PMMPW_H, &PMMCTL0_H
BIS.B #PMMREGOFF, &PMMCTL0_L
BIC.B #SVSHE, &PMMCTL0_L
MOV.B #000h, &PMMCTL0_H
BIS #CPUOFF+OSCOFF+SCG0+SCG1, SR
After this process, the device enters LPM3.5 if modules connected to the RTC LDO are enabled, and it enters LPM4.5 if none of the modules connected to the RTC LDO are enabled.
