TMP92CM22 3.3.3 System Clock Controller The system clock controller generates the system clock signal (f ) for the CPU core and SYS internal I/O. It is used as input that fc outputted from high-frequency oscillation circuit and PLL (Clock doubler) SYSCR1, SYSCR1 sets the high-frequency clock gear to either 1, 2, 4, 8, or 16 (fc, fc/2, fc/4, fc/8, or fc/16). These functions can reduce the power consumption of the equipment in which the device is installed. Single clock

TMP92CM22 3.3.4 Clock Doubler (PLL) PLL outputs the f clock signal, which is four times as fast as f . A reset initializes PLL OSCH PLL to stop status, setting to PLLCR register is needed before use. Like an oscillator, this circuit requires time to stabilize. This is called the lockup time. Note 1: Input frequency limitation for PLL The limitation of input frequency (High-frequency oscillation) for PLL is the following. f = 4 to 10 MHz (Vcc = 3.0 V to 3.6 V) OSCH Note 2: PLLCR
