You can the access the RTC from <code>/dev/rtc0</code> or with the <code>hwclock</code> command (from the <code>util-linux</code> package on Debian based GNU/Linux distributions.

			The RTC clock selected also holds 64 bytes of RAM available to the user to store data as long as the RTC chip is powered (which includes the supercapacitor backup power).<br />
			To get access to this memory you will need to activate the following conigurations in your kernel :
			CONFIG_RTC_NVMEM=y
			CONFIG_NVMEM=y
			CONFIG_NVMEM_SYSFS=y
			When booted with a kernel with NVMEM support activated (with the PCF85363 RTC support, either built-in or as module with module loaded) you will get access to the RAM bytes under <code>/sys</code> in the following file :
			/sys/bus/nvmem/devices/pcf85363-0/nvmem
			You can then use it as a regular file with a limited size of 64 bytes.
			echo "NVMEM Test" > /sys/bus/nvmem/devices/pcf85363-0/nvmem
			cat /sys/bus/nvmem/devices/pcf85363-0/nvmem

			=== Activate main (debug) UART ===
			The main UART (Serial / tty) used by the Linux kernel and base system to output messages (primary UART, where a login console will also be present at the end of the boot process) is not active by default on most distributions.<br />
			On the Raspberry Pi, if this UART is activated it will be present on GPIO 14 (transmit) and 15 (receive). Note that GPIO 14 is pin 8 on the GPIO header, while GPIO 15 is pin 10 (P5 Connector in Connectors section above).
