requirement between VCC33 and VCC15, but does not mention any timing parameters.
The following are the power sequencing requirements that must be followed:
Updated Peripheral Bus Interface (PBI) timings
Table 27 in the 80331 datasheet must be updated.
Table 27 must have the following values:
ATU PM_CAP[5] text must be updated
Table 140, bit[5] reads as follows: DSI – This field is set to 0
device specific initialization sequence following the transition to the D0 uninitialized state.
It must be changed to the following: DSI – This field is set to 0
