Initial power-on defaults
Upon application of power to the device, the register bits will initially power-on in the state
indicated in
Table 9.
1. All other control bits power up in an undetermined state.
Table 10.
1. Leap year occurs every four years (for years evenly divisible by four), except for years evenly divisible by
Initial
power-up
Condition
100. The only exceptions are those years evenly divisible by 400 (the year 2000 was a leap year, year
2100 is not).
