No. RST7.5 is a maskable interrupt on the 8085, not the 8086/8088.
The TRAP interrupt is non-maskable.
Type-2 interrupt is called NMI (Non-maskable interrupt).May occur when 8086 receives a low to high transition on it's interrupt response.Could be used for handling critical situations like power failure detection.
Maskable Interrupt
8086 have 5 interrupt lines.
yes.
interrupts in 8085 are basically classified into two types: 1.Maskable 2.Non maskable maskable interrupts are those which can be delayed.This is done by masking off the interrupts which are not required. Maskable interrupts are:RST 7.5,RST 6.5,RST 5.5 and INTR <decreasing order of priority>
There is no parity interrupt on the 8085 or 8086/8088. If you mean a memory parity interrupt, that is a function of system design, not a function of the particular microprocessor involved. Generally, a memory parity error is fatal, so one would typically place it on a non-maskable interrupt, such as TRAP on the 8085, or INT 2 (NMI) on the 8086/8088. This assumes, of course, that the memory parity error does not just crash the processor.
There are two hardware interrupts in the 8086/8088. INTR, which is maskable, and NMI, which is not.
Finishes the current executing instruction and then serves the interrupt.
A non-maskable interrupt is an interrupt that cannot be blocked, or masked, by the processor. In the 8085, TRAP is such an interrupt. If TRAP goes high and stays high, an interrupt vector sequence at address 24H will occur, and there is nothing the processor can do to prevent that.However, external hardware can accomplish the same thing. In a project that I designed, I needed a fourth single pin interrupt beyond RST5.5, RST6.5, and RST7.5, but I needed it to be maskable, so I built a flip flop in hardware that I could set or reset which would be AND'ed with the interrupt request to generate a maskable TRAP.
The 8086 interrupt priorities are concerned ,software interrupt have the highest priority,followed by NMI ,followed by INTR.The lowest priority signals are unmaskable interrupts.
Four of the interrupts in the Intel 8085 (INTR, RST5.5, RST6.5, and RST7.5) are maskable, while one interrupt (TRAP) is non-maskable.The eight RSTx type of software "interrupts" are not really interrupts, but if they were treated as interrupts, they would be non-maskable.
