Electrical characteristics

Freescale Semiconductor

The DC electrical characteristics are dependent on the PAD3V5V bit value.

3.2.2

NVUSRO[OSCILLATOR_MARGIN] field description

Table 5 shows how NVUSRO[OSCILLATOR_MARGIN] controls the device configuration.

The main external crystal oscillator consumption is dependent on the OSCILLATOR_MARGIN bit value.

3.2.3
