There is no STAX for HL register pair because the data transfer for STAX can be done through XCHG command.
For ex: to transfer the data to the memory loaction specified by the HL pair we do as follows:
XCHG
STAX D
for DE pair and BC pair we can directly do it using STAX

How do you do addition of 32 bit numbers in 8085?
In order to add 32 bit numbers in the 8085, you need to add them 8 bits at a time, tracking the carrys between each add. LXI B,first_number LXI H,second_number LXI D,result LDAX B ;first byte - no carry in ADD M STAX D INX B; point to next byte INX D INX H LDAX B ;second byte - carry in ADC M ;note the ADC instead of ADD STAX D INX B; point to next byte INX D INX H LDAX B ;third byte - carry in ADC M STAX D INX B; point to next byte INX D INX H LDAX B ;fourth - carry in ADC M STAX D

Write a 8085 microprocessor program to check whether a give number is even or odd?
Lxi h, 2000h mov a,m mov b,a inx h mov a,m add b sta 2002h hlt
What would be a program to add two hexadecimals using 8085 microprocessor?
Lxi h,8000h // hl pointes to the location 8000 mov a,m // the value at 8000 copied to accumulator inx h // increment hl add m // add values at 8000 and 8001 hlt // quit the program
What is default value of stack pointer in 8085?
its FF (H)
What is 8085 mpu architecture?

What happens when POP H instruction is executed in 8085?
The POP H instruction in the 8085 copies the top of stack to the HL register and then increments the stack pointer by 2. In C pseudo code, the sequence is L = *(SP++); H = *(SP++);
How many 8 bit register in 8085?
There are seven 8 bit registers in the 8085. A, B, C, D, E, H, and L
