1. I = input, O = output, S = supply.
2. Function availability depends on the chosen device.
3. The PC14 and PC15 I/Os are only configured as OSC32_IN/OSC32_OUT when the LSE oscillator is ON
(by setting the LSEON bit in the RCC_CSR register). The LSE oscillator pins OSC32_IN/OSC32_OUT can
be used as general-purpose PH0/PH1 I/Os, respectively, when the LSE oscillator is off (after reset, the
LSE oscillator is off). The LSE has priority over the GPIO function. For more details, refer to Using the
OSC32_IN/OSC32_OUT pins as GPIO PC14/PC15 port pins section in the STM32L151xx, STM32L152xx
and STM32L162xx reference manual (RM0038).
4. The PH0 and PH1 I/Os are only configured as OSC_IN/OSC_OUT when the HSE oscillator is ON (by
setting the HSEON bit in the RCC_CR register). The HSE oscillator pins OSC_IN/OSC_OUT can be used
as general-purpose PH0/PH1 I/Os, respectively, when the HSE oscillator is off (after reset, the HSE
oscillator is off). The HSE has priority over the GPIO function.
