ULP, pack two 16-bit measurements in one 32-bit register (r0,r1,r2,r3)

Hi,
I am working on a project with ESP32 where I read 16-bit data from an IMU sensor in deep-sleep, hence with ULP.
In order to downsize the data stored in RTC_SLOW_MEM region I would like to save 2 16-bit measurements in one 32-bit register (r0,r1,r2,r3), though I don't know if this is possible. Any ideas? Thank you!

R0-R3 are 16 bit registers.

ULP can only access the lower 16 bits of each 32-bit word in RTC slow memory so that's not possible.

Ok!, thx for your quick reply
