- * Definitions for the Motorola MC146818A Real Time Clock.
- * They also apply for the (compatible) Dallas Semicontuctor DS1287A RTC.
- *
- * Though there are undoubtedly other (better) sources, this material was
- * culled from the DEC "KN121 System Module Programmer's Reference
- * Information."
- *
- * The MC146818A has 16 registers.  The first 10 contain time-of-year
- * and alarm data.  The rest contain various control and status bits.
- *
- * To read or write the registers, one writes the register number to
- * the RTC's control port, then either reads from or writes the new
- * data to the RTC's data port.  Since the locations of these ports
- * and the method used to access them can be machine-dependent, the
- * low-level details of reading and writing the RTC's registers are
- * handled by machine-specific functions.
- *
- * The time-of-year and alarm data can be expressed in either binary
- * or BCD, and they are selected by a bit in register B.
- *
- * The "hour" time-of-year and alarm fields can either be expressed in
- * AM/PM format, or in 24-hour format.  If AM/PM format is chosen, the
- * hour fields can have the values: 1-12 and 81-92 (the latter being
- * PM).  If the 24-hour format is chosen, they can have the values
- * 0-24.  The hour format is selectable by a bit in register B.
- * (XXX IS AM/PM MODE DESCRIPTION CORRECT?)
- *
- * It is assumed the if systems are going to use BCD (rather than
- * binary) mode, or AM/PM hour format, they'll do the appropriate
- * conversions in machine-dependent code.  Also, if the clock is
- * switched between BCD and binary mode, or between AM/PM mode and
- * 24-hour mode, the time-of-day and alarm registers are NOT
- * automatically reset; they must be reprogrammed with correct values.
