RECOMMENDED PMU MODE SWITCHING SEQUENCES
To minimize any possible aberrations and voltage spikes on the DUT output, specific mode switching sequences are recommended for the
following transitions:
•
•
•
PMU Disable to PMU Enable
Step 1: See Table 38 for state of registers in PMU disabled mode.
Table 38.
Register
PE/PMU Enable Register, ADDR[4:0] = 0x0C
PMU State Register, ADDR[4:0] = 0x0E
Step 2: Write to Register ADDR[4:0] = 0x0E (see Table 39).
Table 39.
