After the POR counter times out, the XTAL Counter is enabled to count a total of 16 system clock pulses. The devices are held in the Reset state until both the POR Counter and XTAL counter have timed out. After the 64K Series devices exit the Power-On Reset state, the eZ8 CPU fetches the Reset vector. Following Power-On Reset, the POR status bit in the Watch-Dog Timer Control (WDTCTL) register is set to 1. Figure 8 illustrates Power-On Reset operation. Refer to the Electrical Characteristics chapter for the POR threshold voltage (VPOR). Figure 8. Power-On Reset Operation) Voltage Brown-Out Reset The devices in the 64K Series provide low Voltage Brown-Out (VBO) protection. The VBO circuit senses when the supply voltage drops to an unsafe level (below the VBO threshold voltage) and forces the device into the Reset state. While the supply voltage remains below the Power-On Reset voltage threshold (VPOR), the VBO block holds the device in the Reset state. After the supply voltage again exceeds the Power-On Reset voltage threshold, the devices progress through a full System Reset sequence, as described in the Power-On Reset sec- VCC = 0.0V VCC = 3.3V VPOR VVBO Primary Oscillator Internal RESET signal Program Execution Oscillator Start-up XTAL WDT Clock POR counter delay counter delay Not to Scale |
