341 / 365 page  341 4317K–AVR–03/2013 AT90PWM2/3/2B/3B Note: 1. For compatibility with future devices, reserved bits should be written to zero if accessed. Reserved I/O memory addresses should never be written. 2. I/O Registers within the address range 0x00 - 0x1F are directly bit-accessible using the SBI and CBI instructions. In these registers, the value of single bits can be checked by using the SBIS and SBIC instructions. 3. Some of the status flags are cleared by writing a logical one to them. Note that, unlike most other AVRs, the CBI and SBI instructions will only operate on the specified bit, and can therefore be used on registers containing such status flags. The CBI and SBI instructions work with registers 0x00 to 0x1F only. 4. When using the I/O specific commands IN and OUT, the I/O addresses 0x00 - 0x3F must be used. When addressing I/O Registers as data space using LD and ST instructions, 0x20 must be added to these addresses. The AT90PWM2/2B/3/3B is a complex microcontroller with more peripheral units than can be supported within the 64 location reserved in Opcode for the IN and OUT instructions. For the Extended I/O space from 0x60 - 0xFF in SRAM, only the ST/STS/STD and LD/LDS/LDD instructions can be used. 0x1A (0x3A) GPIOR2 GPIOR27 GPIOR26 GPIOR25 GPIOR24 GPIOR23 GPIOR22 GPIOR21 GPIOR20 page 27 0x19 (0x39) GPIOR1 GPIOR17 GPIOR16 GPIOR15 GPIOR14 GPIOR13 GPIOR12 GPIOR11 GPIOR10 page 27 0x18 (0x38) Reserved – – – – – – – – 0x17 (0x37) Reserved – – – – – – – – 0x16 (0x36) TIFR1 – –ICF1 – – OCF1B OCF1A TOV1 page 130 0x15 (0x35) TIFR0 – – – – – OCF0B OCF0A TOV0 page 102 0x14 (0x34) Reserved – – – – – – – – 0x13 (0x33) Reserved – – – – – – – – 0x12 (0x32) Reserved – – – – – – – – 0x11 (0x31) Reserved – – – – – – – – 0x10 (0x30) Reserved – – – – – – – – 0x0F (0x2F) Reserved – – – – – – – – 0x0E (0x2E) PORTE – – – – – PORTE2 PORTE1 PORTE0 page 81 0x0D (0x2D) DDRE – – – – – DDE2 DDE1 DDE0 page 81 0x0C (0x2C) PINE – – – – – PINE2 PINE1 PINE0 page 81 0x0B (0x2B) PORTD PORTD7 PORTD6 PORTD5 PORTD4 PORTD3 PORTD2 PORTD1 PORTD0 page 80 0x0A (0x2A) DDRD DDD7 DDD6 DDD5 DDD4 DDD3 DDD2 DDD1 DDD0 page 80 0x09 (0x29) PIND PIND7 PIND6 PIND5 PIND4 PIND3 PIND2 PIND1 PIND0 page 81 0x08 (0x28) PORTC PORTC7 PORTC6 PORTC5 PORTC4 PORTC3 PORTC2 PORTC1 PORTC0 page 80 0x07 (0x27) DDRC DDC7 DDC6 DDC5 DDC4 DDC3 DDC2 DDC1 DDC0 page 80 0x06 (0x26) PINC PINC7 PINC6 PINC5 PINC4 PINC3 PINC2 PINC1 PINC0 page 80 0x05 (0x25) PORTB PORTB7 PORTB6 PORTB5 PORTB4 PORTB3 PORTB2 PORTB1 PORTB0 page 80 0x04 (0x24) DDRB DDB7 DDB6 DDB5 DDB4 DDB3 DDB2 DDB1 DDB0 page 80 0x03 (0x23) PINB PINB7 PINB6 PINB5 PINB4 PINB3 PINB2 PINB1 PINB0 page 80 0x02 (0x22) Reserved – – – – – – – – 0x01 (0x21) Reserved – – – – – – – – 0x00 (0x20) Reserved – – – – – – – – Address Name Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 Page |
