What type of flags in 8086 and 8088 microprocessor and their uses.?

∙ 12y ago
There are nine flags in the 8086/8088.
- SF - Sign Flag - The result is negative
- ZF - Zero Flag - The result is zero
- AF - Auxillary Carry Flag - A BCD carry occurred
- PF - Parity Flag - Indicates the oddness or evenness of the number of bits
- CF - Carry Flag - An unsigned carry occurred
- OF - Overflow Flag - A signed overflow/carry occurred
- DF - Direction Flag - Controls the direction of repeated string operations
- IF - Interrupt Flag - Enables or disables interrupts
- TF - Trace Flag - Controls the debug single step interrupt
In general, most of these flags are set as a result of some arithmetic or logical instruction and can be tested using the conditional branch instructions. Exceptions are DF, which controls the directionality of repeated string operations, IF, which controls interrupts, and TF, which controls debugging.

How do you fix a frozen tv screen?
Sounds like a digital TV. Try unplugging it for awhile and then plugging it back in. That forces a `hard reset' of the microprocessor and should free the screen. If not, you've got some other type of issue either with the TV itself or with the source.
