4.2.10 Register – Timestamp
Three registers are utilized to maintain a timestamp that increments on the microcontroller after power up.
These are all set to 0 upon power up or a microcontroller reset. The first two registers 8208 and 8209 are
internally combined into a single 32 bit register and incremented each second.
The last register 8210
maintains the millisecond count and will count from 0 to 999 and start over again.
