|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 01. On the TI-83 Plus Silver Edition, this port has no effect.|
Port Numbers: 41h through 44h
Function: Clock Setting Ports
These ports are used to set a new value to the TI-84+'s timer.
Reading from the port simply gives the last value outputted to the port. These ports are nothing more than a simple external "register" where the new clock values are stored.
Like the actual clock ports (ports 45h-48h), these are arranged so the first port is the least significant byte in a 32-bit value, which gives the number of seconds after midnight, January 1st, 1997.
