Real Time Clock (RTC)

The SoC contains a Motorola MC146818B-compatible real-time clock with 242 bytes of

battery-backed RAM. The real-time clock performs two key functions—keeping track of

the time of day and storing system data, even when the system is powered down. The

RTC operates on an external 32.768 KHz crystal and a 3.3 V battery. An option is also

provided to internally generate the 32.768 KHz clock.

The RTC supports two lockable memory ranges. By setting bits in the configuration

space, two 8-byte ranges can be locked to read and write accesses. This prevents

unauthorized reading of passwords or other system security information.

The RTC supports a date alarm that allows for scheduling a wake up event up to 30

days in advance.

Signal Descriptions

See Chapter 2.0, “Physical Interfaces” for additional details.

The signal description table has the following headings:

• Signal Name: The name of the signal/pin

• Direction: The buffer direction can be either input, output, or I/O (bidirectional)

• Type: The buffer type found in Chapter 4.0, “Electrical Characteristics”

• Description: A brief explanation of the signal’s function
