T1SC[6:0]
Timer 1 Secondary Chain
[6:0]
These register bits provide the ability to read the
secondary divide by 100 chain of timer 1. This chain is
enabled with the T1PS bit (0xFE05, bit 4). When enabled,
a value of 100 (decimal) in this register triggers
advancement of the final timer 1 divider chain.
Register: 0xFE08
Timer 1 Final Chain (T1FC)
Read Only
T1FC[7:0]
Timer 1 Final Chain
[7:0]
These register bits provide the ability to read the final
timer 1 divider chain. The timer expires when the value
of this divider chain is equal to the value of the
register (
). When this happens,
the T1EXP bit (0xFE05, bit 7) will be set and an interrupt
will be generated to the microcontroller, through the
register, if the T1IEN bit (0xFE05, bit 0)
is set.
