The LPECO provides high-frequency clocking using an external crystal connected to the LPECO_IN and LPECO_OUT pins.
It can be thought of as an ECO that operates during low power modes and, when used in conjunction with the PLL, it generates CPU and peripheral clocks up to the device's maximum frequency. A fractional divider allows the real-time clock (RTC) to use the LPECO during low power modes, however, the LPECO has significantly higher current consumption than the WCO.
The pins connected to the external crystal must be configured to operate in analog drive mode with HSIOM connection set to GPIO control (HSIOM_SEL_GPIO).
