IHRC: Internal high-speed oscillator RC type. ILRC: Internal low-speed oscillator RC type. Note: 1. SIO, MSP and UART inactive in slow mode and green mo de, because the clock source doesn’t exist. Use firmware to disable SIO, MSP, UART function before inserting slow mode and green mode. 2. In IHRC_RTC mode, STPHX only controls IHRC, not Ext. 32K. STPHX=0, IHRC actives. STPHX=1, IHRC stops. 5.2 NORMAL MODE The Normal Mode is system high clock operating mode. The system clock source is from high speed oscillator. The program is executed. After power on and any reset trigger released, the system inserts into normal mode to execute program. When the system is wake-up from power down mode, the system also inserts into normal mode. In normal mode, the high speed oscillator actives, and the power consumption is largest of all operating modes. The program is executed, and full functions are controllable. The system rate is high speed. The high speed oscillator and internal low speed RC type oscillator active. Normal mode can be switched to other operating modes through OSCM register. Power down mode is wake-up to normal mode. Slow mode is switched to normal mode. Green mode from normal mode is wake-up to normal mode. |
