AT91RM9200
• Four operating modes:
• System peripheral to facilitate debug of Atmel’s ARM-based systems
• Composed of the following functions
• Two-pin UART
• Debug Communication Channel Support
• Chip ID Registers
• 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)
– the Master Clock MCK
– the USB Clocks, UHPCK and UDPCK, respectively for the USB Host Port and the
– Programmable automatic PLL switch-off in USB Device suspend conditions
– up to thirty peripheral clocks
– four programmable clock outputs PCK0 to PCK3
– Normal Mode, Idle Mode, Slow Clock Mode, Standby Mode
– Two-pin UART
– Debug Communication Channel (DCC) support
– Chip ID Registers
– Implemented features are 100% compatible with the standard Atmel USART
– Independent receiver and transmitter with a common programmable Baud Rate
– Even, Odd, Mark or Space Parity Generation
– Parity, Framing and Overrun Error Detection
– Automatic Echo, Local Loopback and Remote Loopback Channel Modes
– Interrupt generation
– Support for two PDC channels with connection to receiver and transmitter
– Offers visibility of COMMRX and COMMTX signals from the ARM Processor
– Interrupt generation
– Identification of the device revision, sizes of the embedded memories, set of
– 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
