Code Example
------------
.. code-block:: python
from periphery import MMIO
# Open am335x real-time clock subsystem page
rtc_mmio = MMIO(0x44E3E000, 0x1000)
# Read current time
rtc_secs = rtc_mmio.read32(0x00)
rtc_mins = rtc_mmio.read32(0x04)
rtc_hrs = rtc_mmio.read32(0x08)
print("hours: {:02x} minutes: {:02x} seconds: {:02x}".format(rtc_hrs, rtc_mins, rtc_secs))
rtc_mmio.close()
# Open am335x control module page
ctrl_mmio = MMIO(0x44E10000, 0x1000)
# Read MAC address
mac_id0_lo = ctrl_mmio.read32(0x630)
mac_id0_hi = ctrl_mmio.read32(0x634)
print("MAC address: {:04x}{:08x}".format(mac_id0_lo, mac_id0_hi))
ctrl_mmio.close()
