PIO Controllers
AT91SAM9261S
• Chip ID Registers
• ICE Access prevention
• Three PIO Controllers, each controlling up to 32 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)
• Synchronous output, provides Set and Clear of several I/O lines in a single write
– Offers visibility of COMMRX and COMMTX signals from the ARM Processor
– Identification of the device revision, sizes of the embedded memories, set of
– Enables software to prevent system access through the ARM Processor’s ICE
– Prevention is made by asserting the NTRST line of the ARM Processor’s ICE
– PIOA has 32 I/O Lines
– PIOB has 32 I/O Lines
– PIOC has 32 I/O Lines
– Input change interrupt
– 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
