Characteristics
Expression2
8 Delay from RESET assertion to all pins at reset value3
9 Required RESET duration4
• Power on, external clock generator, PLL disabled
• Power on, external clock generator, PLL enabled
• Power on, internal oscillator
• During STOP, XTAL disabled (PCTL Bit 16 = 0)
• During STOP, XTAL enabled (PCTL Bit 16 = 1)
• During normal operation
