After a signed number operation, the programmer should check C and Ov flags. (2pts) True False DB is used to store fixed values in EEPROM so they stay even after poweroff. (2pts) O True False XORWE and XORLW can be used to compare WREG with the operand. (2pts) True False DB instruction has no opcode in PIC because it is an assembler directive (2pts) True False The CLRF instruction always makes the Z flag o. (2pts) True False PIC has internal hardware to tell if a number is unsigned. (2pts) True False
