... The Port E pins are tri-stated when a reset condition becomes active, even if the clock is not running. Port E also serves the functions of various special features of the ATmega8515 as listed on page 74. Reset input. A low level on this pin for longer than the minimum pulse length will gener- ate a reset, even if the clock is not running ...

... 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 $00 to $1F only. 2512JS–AVR–10/06 ATmega8515(L) 9 ...
