5.14 Store Loop Adapter Interrupt Flag Byte
This table describes the bits of the store loop adapter interrupt flag
byte. This byte is updated by the software interrupt service routine when
a level 7 hardware interrupt occurs.

¦ Bit ¦ Definition ¦
+-------+----------------------------------------------------------------¦
¦ Bit 7 ¦ 1 = The level 7 interrupt is not from the store loop adapter. ¦
+-------+----------------------------------------------------------------¦
¦ Bit 6 ¦ 1 = An interrupt occurred when not expected (Bit 0 = 0). ¦
+-------+----------------------------------------------------------------¦
¦ Bit 5 ¦ 1 = More than one interrupt occurred when only one was ¦
¦ ¦ expected (Bit 0 = 1). ¦
+-------+----------------------------------------------------------------¦
¦ Bit 4 ¦ Not used, always zero (0). ¦
+-------+----------------------------------------------------------------¦
¦ Bit 3 ¦ Not used, always zero (0). ¦
+-------+----------------------------------------------------------------¦
¦ Bit 2 ¦ Not used, always zero (0). ¦
+-------+----------------------------------------------------------------¦
¦ Bit 1 ¦ 1 = A store loop adapter level 7 hardware interrupt has ¦
¦ ¦ occurred. ¦
+-------+----------------------------------------------------------------¦
¦ Bit 0 ¦ 1 = A store loop adapter level 7 hardware interrupt is ¦
¦ ¦ expected. ¦
