PS/1 Digital Core Supply Voltage for Domain 1

Decouple each with a 220 nF ceramic capacitor.

All VDDI1 pins must be connected to each other.

-

PS/A Digital Pad Supply Voltage for Domain A

Connect decoupling capacitors to adjacent

VDDP/VSS 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 VDDPA.

-

PS/B Digital Pad Supply Voltage for Domain B

Connect decoupling capacitors to adjacent

VDDP/VSS pin pairs as close as possible to the pins.

Note: The on-chip voltage regulators and all ports

except P5, P6, and P15 are fed from supply

voltage VDDPB.

PS/-- Digital Ground

All VSS pins must be connected to the ground-line

or ground-plane.

1) To generate the reference clock output for bus timing measurement, fSYS must be selected as source for

EXTCLK and P2.8 must be selected as output pin. Also the high-speed clock pad must be enabled. This

configuration is referred to as reference clock output signal CLKOUT.
