Synopsis
Port Numbers: 41h through 44h
Function: Clock Setting Ports
These ports are used to set a new value to the TI-84+'s timer.
For further information on the clock, read the documentation for ports 40h and 45h-48h.
Comments
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.
