6 PUSH B<\/p>\n
7 MOV A, L<\/p>\n
\u2026.<\/p>\n
20 POP H<\/p>\n
What is stored in the stack pointer register after the execution of Line 1?<\/p>\n
What is the memory location of the stack where the first byte is stored?<\/p>\n
What is stored in memory location 03FEH when line 5 (PUSH H) is executed?<\/p>\n
After the execution of line 6 (PUSH B), what is the address in the stack pointer register, and what is stored in stack memory location 03FDH?<\/p>\n
Specify the contents of register pair HL after the execution of line 20 (POP H).<\/p>\n
Write a program to add the two Hex numbers 7A and 46 and to store the sum at memory location XX98H and the flag status at location xx97H<\/p>\n
Write a program to meet the following specifications:<\/p>\n
Initialize the stack pointer register at XX99H<\/p>\n
Clear the memory locations starting from XX90H to XX9FH<\/p>\n
Load register pairs, B, D, and H with data 0237H, 1242H, and 4087H, respectively<\/p>\n
Push the contents of the register pairs B, D, and H on the stack<\/p>\n
Execute the program and verify the memory locations from XX90H to XX9FH<\/p>\n
The following program has a subroutine located at location 2060H. Read the program and answer the questions given at the end of the program<\/p>\n
2000 LXI SP, 20CDH<\/p>\n
2003 LXI H, 0008H<\/p>\n

2008 CALL 2060H<\/p>\n
200B OUT 01H<\/p>\n
\u2026. \u2026\u2026<\/p>\n
\u2026\u2026 \u2026\u2026<\/p>\n
2060 PUSH H<\/p>\n
2061 PUSH B<\/p>\n
MVI B, 05H<\/p>\n
LXI H, count<\/p>\n
\u2026. \u2026\u2026<\/p>\n
POP B<\/p>\n
POP H<\/p>\n
RET<\/p>\n
When the execution of the CALL instruction located at 2008H-200AH is completed, list the contents stored at 20CCH and 20CBH, the contents of the program counter and the contents of the stack pointer register<\/p>\n
List the stack locations and their contents after the execution of the instructions PUSH H and PUSH B in the subroutine<\/p>\n
List the contents of the stack pointer register after the execution of the PUSH B located at 2061H<\/p>\n
List the contents of the stack pointer register after the execution of the RET instruction<\/p>\n","protected":false},"excerpt":{"rendered":"
