36 / 114 page ![]() MPC5607B Microcontroller Data Sheet, Rev. 10 Electrical characteristics NXP Semiconductors 36 4.2.2 NVUSRO[OSCILLATOR_MARGIN] field description The fast external crystal oscillator consumption is dependent on the OSCILLATOR_MARGIN bit value. Table 9 shows how NVUSRO[OSCILLATOR_MARGIN] controls the device configuration. 4.2.3 NVUSRO[WATCHDOG_EN] field description The watchdog enable/disable configuration after reset is dependent on the WATCHDOG_EN bit value. Table 10 shows how NVUSRO[WATCHDOG_EN] controls the device configuration. 4.3 Absolute maximum ratings 2 Default manufacturing value is ‘1’. Value can be programmed by customer in Shadow Flash. Table 9. OSCILLATOR_MARGIN field description1 1 See the device reference manual for more information on the NVUSRO register. Value2 2 Default manufacturing value is ‘1’. Value can be programmed by customer in Shadow Flash. Description 0 Low consumption configuration (4 MHz/8 MHz) 1 High margin configuration (4 MHz/16 MHz) Table 10. WATCHDOG_EN field description Value1 1 Default manufacturing value is ‘1’. Value can be programmed by customer in Shadow Flash. Description 0 Disable after reset 1 Enable after reset Table 11. Absolute maximum ratings Symbol Parameter Conditions Value Unit Min Max VSS SR Digital ground on VSS_HV pins — 0 0 V VDD SR Voltage on VDD_HV pins with respect to ground (VSS) —–0.3 6.0 V VSS_LV SR Voltage on VSS_LV (low voltage digital supply) pins with respect to ground (VSS) —VSS –0.1 VSS +0.1 V VDD_BV SR Voltage on VDD_BV (regulator supply) pin with respect to ground (VSS) —–0.3 6.0 V Relative to VDD –0.3 VDD +0.3 VSS_ADC SR Voltage on VSS_HV_ADC0, VSS_HV_ADC1 (ADC reference) pins with respect to ground (VSS) —VSS –0.1 VSS +0.1 V VDD_ADC SR Voltage on VDD_HV_ADC0, VDD_HV_ADC1 (ADC reference) pins with respect to ground (VSS) —–0.3 6.0 V Relative to VDD VDD − 0.3 VDD +0.3 |
