Peripheral operation during LPM2

Hi,

My customer is using MSP430F5255.
And there are a few questions relating LPM2.

1) While the chip is in LPM2 and UART data(115200bps) come from an external device, the data are lost ?
If ACLK is used as UART clock, no data drop happens ?

2) Suppose Timer_A/B modules are clocked by an external pin(TA0CLK for example), Timer_A/B can be used during LPM2, correct ?

3) Suppose slow-wakeup mode is used in the system, if external interrupts happens during 150usec wakeup period, any interrupt drop happens? Or all interrupts are kept and handled properly after wakeup?

Thanks and regards,
KoT
