Pad Types

In the device the following types of pads are available for system pins and functional port pins:

S = Slow1

M = Medium1,2

F = Fast1,2

I = Input only with analog feature1

J = Input/Output with analog feature

X = Oscillator

2.4.4

System Pins

The system pins are listed in Table 4.

VSSPLL

PLL ground

VSSOSC

Oscillator ground

VLCD

LCD supply option

VPP

9 V - 12 V flash test analog write signal

1 Decoupling capacitors must be connected between these pins and the nearest V

SS12 pin.

2 All stepper motor supplies need to be at same level (3.3 V or 5 V).

3 Refer to LCD segment of Reference manual for usage of VLCD as supply/reference voltage source.

4 This signal needs to be connected to ground during normal operation.

1. Refer to Section 3.6, “I/O Pad Electrical Characteristics, for details

2. All medium and fast pads are in slow configuration by default at reset and can be configured as fast or medium (refer to

PCR.SRC in the device reference manual, Pad Configuration Registers (PCR0 - PCR120)).
