//! with a very accurate, temperature-compensated, integrated real-time clock
//! (RTC) including 236/256 bytes of battery-backed SRAM, depending on the model.

//!
//! The RTC maintains seconds, minutes, hours, day, date, month, and year
//! information. The date at the end of the month is automatically adjusted for
//! months with fewer than 31 days, including corrections for leap year. The
//! clock operates in either the 24-hour or 12-hour format with an AM/PM
//! indicator. Two programmable time-of-day alarms and a programmable
//! square-wave output are provided. Address and data are transferred serially
//! through an I2C bidirectional bus.

//! A precision temperature-compensated voltage reference and comparator
//! circuit monitors the status of VCC to detect power failures, to provide a
//! reset output, and to automatically switch to the backup supply when
