Function
Classification
PLL RC component connect pin
O Connect a capacitor and resistor between this pin and VSS4. This pin Analog Output
outputs “L” during initial reset.
I
Test1 Pin (Internal pull-down)
This pin must be connected to VSS1.
Test
Crystal oscillator output pin
O
When a crystal oscillator is used, connect it between XTI and XTO. When
an external clock is used, leave this pin open. During initial reset, the output
of this pin is Hi-Z.
Crystal oscillator input pin/ Master Clock input
System Clcok
I
Connect a crystal oscillator between this pin and the XTO pin, or input an
external clock to the XTI pin. When CKM[2:0] bits= 0h, 1h, 2h, input “L”
to this pin.
