3.8.1
The CGU generates all clock signals required within the microcontroller from a single
clock, f
modules are as follow:
• CPU clock: CCLK, SCLK = 26.7 MHz
• CCU6 clock: FCLK = 26.7 MHz
• Other peripherals: PCLK = 26.7 MHz
• Flash Interface clock: CCLK3 = 80 MHz, CCLKn = 80 MHz and CCLK = 26.7 MHz
In addition, different clock frequency can output to pin CLKOUT(P0.0). The clock output
frequency can further be divided by 2 using toggle latch (bit TLEN is set to 1), the
resulting output frequency has 50% duty cycle.
