I/O and memory operations are differentiated by this status signal. When it is HIGH, I/O operation takes place and when LOW, memory operation takes place. This signal is combined with read/write in order yo generate I/O and memory control signals.
There is no exit instruction in the 8085. Do you mean return, as in from a function or interrupt? If so, the instruction is RET.
It provides timing signals.
It is an 8 bit register which is accessable to programmer and is main fuction is to perfom all arithmetic and logical function.
The TMP register in the 8085 is used to hold temporary results of operations. You cannot directly manipulate it, so you should just pretend it is not there.
The initials IOM might mean different things to different people depending on your background and culture. Globally, IOM can stand for the Institute of Medicine or the International Organization for Medicine, amongst other things. IOM might also refer to the Iomega Corporation, or, within computing, an Integrated Object Model. IOM depends entirely on your context and what specifically you are searching for.
8085 is a microprocessor designed by Intel
I know of no PMW pin or PMW instruction in the 8085. Please restate the question. If you are asking about PWM, or pulse width modulation, please note that that is not an 8085 specific thing. It would be a function of system design, and you could achieve PWM with programming, but the answer would depend on the particulars of that system design.

The 8085 was replaced with the 8086/8088. As such, there is no 16 bit version of the 8085.
The 8085 has a single +5V power supplyThe 8085 has a multiplexed low order address busThe 8085 has extra single pin interrupts, TRAP, RST7.5, RST6.5, and RST5.5The 8085 has serial I/O pins SID and SODThe 8085 has maskable interrupts and the RIM/SIM instructionThe 8085 includes the functionality of the 8224 clock genereator and 8228 system controllerThe 8085 added several 16 bit operations
