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.

∙ 14y agomasakable interrupts-in this case when the interrupt is masked. the microprocessor will not respond to the interrupt even if the interrupt is activated. the interrupt which can be masked are called masakble interrupt. for example - RST7.5, RST6.5, RST5.5.
non- masakable interrupts-the interrupts which cannot be masked are called non-masakable interrupts. for example - trap. a trap is a non -masakable edge and level triggered interrupt. it has highest priority among all the interrupts . this interrupt transfer microprocessor control to location to 0024H

Is rst7.5 is a maskable interrupt in 8086?
No. RST7.5 is a maskable interrupt on the 8085, not the 8086/8088.
What is the Intel 8085?
Intel 8085 is a microprocessor that is used in various electronics devices.
What is masking in 8085?
Masking in the 8085 is when certain interrupts are disabled, or masked, by instruction execution. TRAP is not maskable. INTR, RST7.5, RST6.5, and RST5.5 are maskable as a group with the EI and DI instructions. RST7.5, RST6.5, and RST5.5 are selectively maskable, even after the EI instruction, by using the RIM and SIM instructions.
Why the name 8085 Why the name 8085 for microprocessor?
8085 is a microprocessor designed by Intel
When 8085 processor was invented?
The 8085 was introduced by Intel in 1977.
What is the data size in Intel 8085?
The data size in the 8085 is 8 bits.
What is meant by trap in 8085?
TRAP is a single pin interrupt that is non-maskable in the 8085. It is intended for notification of serious system problems and/or as an aid to a hardware assisted debugger.
What is the use of RST?
RSTn(0-7) is software interrupt & RST(7.5,6.5,5.5) are INTEL's 8085 maskable interrupts their priority is respectively 7.5,6.5,5.5.RSTn.5 is hardware intterrupt and it is controlled by the external pin available on the chip of 8085. it is used to interrupt the microprocessor from its normal execution and tends to execute some ISR(interrupt service routine)
What is the Overview of 8085 microprocessor?
8085 is a 8 bit microprocessor designed by Intel Co.
What is the Intel 8085 used for?
for the purpose of computing.
What is a 8085 microprocessor?
with neat diagram explain the system bus structure of 8085
Why 8085 is a 40 pin ic?
The 8085 is a 40 pin ic because Intel designed it that way.
