Table 4±1. Adapter Check Bit Definitions

Bit	Name	Function
28±21	Channel	This field indicates the active PCI channel at the time of the failure.
20	L/D	List not data: If this bit is set to 1, a PCI list operation was in progress at the time of the
		failure. If this bit is set to 0, a PCI data transfer operation was in progress at the time
		of the failure.
19	R/T	Receive not transmit: If this bit is set to 1, a PCI receive channel operation was in prog-
		ress at the time of the failure. If this bit is set to 0, a PCI transmit channel operation was
		in progress at the time of the failure.
18	R/W	Read not write: If this bit is set to 1, a PCI read operation was in progress at the time
		of the failure. If this bit is set to 0, a PCI write operation was in progress at the time of
		the failure.
		This bit can be used to differentiate between list reads and CSTAT field writes, which
		are both list operations.
7±0	Failure code	This field indicates the type of failure that caused the adapter check.
