257 / 273 page  257 8042A–AVR–07/09 ATmega16HVB/32HVB Notes: 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 $00 - $1F are directly bit-accessible using the SBI and CBI instructions. In these reg- isters, 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 the CBI and SBI instructions will operate on all bits in the I/O register, writing a one back into any flag read as set, thus clearing the flag. 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 $00 - $3F must be used. When addressing I/O regis- ters as data space using LD and ST instructions, $20 must be added to these addresses. The ATmega16HVB/32HVB 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 $60 - $FF in SRAM, only the ST/STS/STD and LD/LDS/LDD instructions can be used. 0x1B (0x3B) PCIFR – – – – – –PCIF1 PCIF0 60 0x1A (0x3A) Reserved – – – – – – – – 0x19 (0x39) Reserved – – – – – – – – 0x18 (0x38) Reserved – – – – – – – – 0x17 (0x37) OSICSR – – – OSISEL0 – – OSIST OSIEN 33 0x16 (0x36) TIFR1 – – – – ICF1 OCF1B OCF1A TOV1 96 0x15 (0x35) TIFR0 – – – – ICF0 OCF0B OCF0A TOV0 96 0x14 (0x34) Reserved – – – – – – – – 0x13 (0x33) Reserved – – – – – – – – 0x12 (0x32) Reserved – – – – – – – – 0x11 (0x31) Reserved – – – – – – – – 0x10 (0x30) Reserved – – – – – – – – 0x0F (0x2F) Reserved – – – – – – – – 0x0E (0x2E) Reserved – – – – – – – – 0x0D (0x2D) Reserved – – – – – – – – 0x0C (0x2C) Reserved – – – – – – – – 0x0B (0x2B) Reserved – – – – – – – – 0x0A (0x2A) Reserved – – – – – – – – 0x09 (0x29) Reserved – – – – – – – – 0x08 (0x28) PORTC – – PORTC5 PORTC4 PORTC3 PORTC2 PORTC1 PORTC0 66 0x07 (0x27) Reserved – – – – – – – – 0x06 (0x26) PINC – – – PINC4 PINC3 PINC2 PINC1 PINC0 66 0x05 (0x25) PORTB PORTB7 PORTB6 PORTB5 PORTB4 PORTB3 PORTB2 PORTB1 PORTB0 78 0x04 (0x24) DDRB DDB7 DDB6 DDB5 DDB4 DDB3 DDB2 DDB1 DDB0 78 0x03 (0x23) PINB PINB7 PINB6 PINB5 PINB4 PINB3 PINB2 PINB1 PINB0 78 0x02 (0x22) PORTA – – – – PORTA3 PORTA2 PORTA1 PORTA0 78 0x01 (0x21) DDRA – – – – DDA3 DDA2 DDA1 DDA0 78 0x00 (0x20) PINA – – – – PINA3 PINA2 PINA1 PINA0 78 Address Name Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 Page |
