The 9th bit of the program counter will be forced to a ‘0’ by any instruction that writes to the PC except for GOTO. See Section 4.7 “Program Counter”.
When an I/O register is modified as a function of itself (e.g. MOVF PORTB, 1), the value used will be that value present on the pins themselves. For example, if the data latch is ‘1’ for a pin configured as input and is driven low by an external device, the data will be written back with a ‘0’.
The instruction TRIS f, where f = 6, causes the contents of the W register to be written to the tri-state latches of PORTB. A ‘1’ forces the pin to a high-impedance state and disables the output buffers before Restore AVR Microcomputer ATTINY44 Eeprom Code.
If this instruction is executed on the TMR0 register (and where applicable, d = 1), the prescaler will be cleared (if assigned to TMR0).
