-
PS/1 Digital Core Supply Voltage for Domain 1
Decouple with a ceramic capacitor, see Table 12
for details.
All V_DDI1 pins must be connected to each other.
-
PS/A Digital Pad Supply Voltage for Domain A
Connect decoupling capacitors to adjacent
V_DDP/V_SS pin pairs as close as possible to the pins.
Note: The A/D_Converters and ports P5, P6, and
P15 are fed from supply voltage V_DDPA.
