33 / 116 page  Rev. 1.10 �� �e���a�� 1�� �01� Rev. 1.10 �� �e���a�� 1�� �01� HT98R068-1 Two Way Radio 8-Bit MCU HT98R068-1 Two Way Radio 8-Bit MCU Operating mode and MCU system clock source is as following table. Operating Mode Control HALT Instruction IDLE COMMAND PLLEN Bit CLKMOD Bit LXTEN Bit LXT Oscillator MCU System Clock MCU Mode Audio Processor System Clock Audio Processor Mode Non Exec�ted Non Exec�ted 1 0 x On PLL No�mal PLL No�mal Exec�ted 1 0 x On PLL HALT Idle Non Exec�ted 1 1 x On LXT Slow PLL No�mal Exec�ted 1 1 x On LXT HALT Idle Exec�ted Exec�ted 0 1 1 On HALT Idle HALT Idle 0 1 0 Off HALT Sleep Note: 1. LXT oscillator is the 32768 Hz oscillator. 2. SST for LXT OSC is 1024 clocks. 3. If PLLEN=0, CLKMOD bit will be set. 4. The Audio Processor must execute Audio Processor idle command via SPI, before MCU Executed HALT instruction or disable PLL (PLLEN=0). The MCU operating mode switch timing are shown in the following figures.
