All standard devices are marked with a mask set number and a date code. Possible High Current in Stop Mode If KBI/IRQ Enabled Description SE96B-IRQ_KBI In stop mode, with the IRQ or KBI pin functions enabled but the IRQ/KBI interrupt disabled, a toggle on the IRQ/KBI pin will turn on the voltage regulator and oscillator, causing the clocks to run. This results in higher stop IDD. In this condition, the CPU is halted (as if in wait mode) and the chip level interrupt is not generated. This higher current condition can also happen if the flag is set at time of stop entry. © Freescale Semiconductor, Inc., 2006, 2007. All rights reserved. Workaround This problem applies to the non-interrupt functions that are shared with IRQ and KBI functions. Because interrupts from IRQ or KBI are disabled, these pins are not used to wake up the MCU from stop. To prevent signals on IRQ or KBI from causing an unexpected partial wakeup from stop in these applications, disable the IRQ and KBI modules just before entering stop mode. Also verify that any previous interrupt flags associated wi...
