9.6
Periodic Interval Timer
20-bit programmable counter plus 12-bit interval counter
9.7
Watchdog Timer
12-bit key-protected Programmable Counter running on prescaled SLCK
Provides reset or interrupt signals to the system
Counter may be stopped while the processor is in debug state or in idle mode
9.8
Real-time Timer
32-bit free-running counter with alarm running on prescaled SLCK
Programmable 16-bit prescaler for SLCK accuracy compensation
9.9
PIO Controllers
Three PIO Controllers. PIO A and B each control 32 I/O lines and PIO C controls 24 I/O lines.
Fully programmable through set/clear registers
Multiplexing of two peripheral functions per I/O line
For each I/O line (whether assigned to a peripheral or used as general-purpose I/O)
– Input change interrupt
– Half a clock period glitch filter
– Multi-drive option enables driving in open drain
– Programmable pull-up on each I/O line
– Pin data status register, supplies visibility of the level on the pin at any time
