Notes 1.
Operation is enabled while the main system clock is selected.
2.
Operation is enabled while the subsystem clock is selected.
3.
Operation is enabled only when TI80 is selected as the count clock.
4.
Operation is enabled only when TI81 is selected as the count clock.
5.
Operation is enabled in both three-wire serial I/O and UART modes while an external clock is being
used.
6.
While in slave mode, an interrupt can be generated when an address match is found.
7.
Operation is enabled when TM80 output is selected (only when TI80 is selected for TM80) as the
count clock.
8.
Maskable interrupt that is not masked
