9.7
Period Interval Timer
20-bit programmable counter plus 12-bit interval counter
9.8
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
9.9
Real-time Timer
32-bit free-running counter with alarm
Programmable 16-bit prescaler for SCLK accuracy compensation
9.10
Shutdown Controller
Software programmable assertion of the SHDW open-drain pin
De-assertion programmable with the pins WKUP0, WKUP1 and FWKUP
9.11
PIO Controllers A and B
The PIO Controllers A and B respectively control 32 and 30 programmable 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
