/**
 * <P> 1-Wire container for 512 byte memory iButton Plus Time, DS1994 and 1-Wire Chip, DS2404.
 * This container encapsulates the functionality of the iButton family
 * type <B>04</B> (hex)</P>
 *
 * <P> This iButton is primarily used as a read/write portable memory device with real-time-clock,
 *  timer and experation features. </P>
 *
 * <H3> Features </H3>
 * <UL>
 *   <LI> 4096 bits (512 bytes) of read/write nonvolatile memory
 *   <LI> 256-bit (32-byte) scratchpad ensures integrity of data
 *        transfer
 *   <LI> Memory partitioned into 256-bit (32-byte) pages for
 *        packetizing data
 *   <LI> Data integrity assured with strict read/write
 *        protocols
 *   <LI> Contains real time clock/calendar in binary
 *        format
 *   <LI> Interval timer can automatically accumulate
 *        time when power is applied
 *   <LI> Programmable cycle counter can accumulate
 *        the number of system power-on/off cycles
 *   <LI> Programmable alarms can be set to generate
 *        interrupts for interval timer, real time clock,
 *        and/or cycle counter
 *   <LI> Write protect feature provides tamper-proof
 *        time data
 *   <LI> Programmable expiration date that will limit
 *        access to SRAM and timekeeping
 *   <LI> Clock accuracy is better than
