Since The vectored Location of RST5.5 lie in Half the location of RST5 and RST6 so it is called RST 5.5(RST 5+1/2 )

Explanation:

Vector Interrrupt Vectored Location

RST 5 0028H

RST 5.5 002CH

RST 6 0030H

Now we add RST5 and RST6 vectored Location's

0028H + 0030H = 0058H

Now Devide The Sum by 2

0058H/2 = 002CH

Which is Vectored Location of RST 5.5.

This You can Check for All other vectored Interrupts TRAP(RST4.5), RST6.5, RST7.5

for 8085 Microprocessor

What is the use of interrupt vector?

An interrupt vector is the memory address of an interrupt handler, or an index into an array called an interrupt vector table or dispatch table. Interrupt vector tables contain the memory addresses of interrupt handlers. When an interrupt is generated, the processor saves its execution state via a context switch, and begins execution of the interrupt handler at the interrupt vector.

Where is interrupt handler and interrupt vector?

In the 8086/8088, the interrupt vector table is the first 1024 bytes of memory. In the 8085, the interrupt vector table is the first 64 bytes of memory if using the RST form of interrupt, otherwise the interrupt vector is provided by the interrupting device, usually in the form of a CALL instruction. The interrupt handler is wherever the interrupt vector points to.
