This port only exists on the the TI-84 Plus and the TI-84 Plus Silver Edition. On the standard TI-83 Plus, it acts as a shadow of port 05. On the TI-83 Plus Silver Edition, this port has no effect.


Port Numbers: 45h through 48h

Function: Clock Current Time Ports

These ports give the current time of the TI-84+'s clock.

For further information on the clock and its use, read the documentation for ports 40h and 41h-44h.


Writes to these ports are ignored. If the clock is off, they will always read 0.

These four parts are arranged so the first port (45h) is the least significant byte in a 32-bit value, which gives the number of seconds after midnight, January 1st, 1997.
