The device has two clock output signals. The CLKOUT1 signal can be configured to output the master oscillator (CLK_M_OSC), EXTDEV_PLL, 32-kHz, or several other internal clocks. See the device-specific TRM for more details. The CLKOUT2 signal can be configured to output the OSC1 input clock, which is referred to as the 32K oscillator (CLK_32K_RTC) in the device-specific technical reference manual, or four other internal clocks. For more information related to configuring these clock output signals, see the CLKOUT Signals section of the device-specific technical reference manual.
