Writing to the Power Control SFR (POWCON, Address 0xC5)
Writing data to the POWCON SFR involves writing 0xA7 into the key SFR (KYREG, Address 0xC1), which is described in Table 126,
followed by a write to the POWCON SFR. For example,
MOV KYREG,#0A7h
MOV POWCON,#10h

Reserved.
Set this bit to turn off the modulators and energy metering DSP circuitry to reduce power if
metering functions are not needed in PSM0 mode.
This bit should be kept at 0 for proper operation.
Set this bit to shut down the core and enter PSM2 mode if in the PSM1 operating mode.
