CPU Bus Unit Numbers

Bits A41000 through A41015 correspond to CPU Bus Units #0 through #15, respectively. When two CPU Bus Units have the same unit number, the bits corresponding to the unit numbers of the CPU Bus Units involved are turned ON.

Network Status Flags

Bits A50200 through A50207 are turned ON to indicate that ports #0 through #7, respectively, are enabled for the SEND(192), RECV(193), and CMND(194). Bits A50208 through A50215 are turned ON to indicate that an error has occurred in ports #0 through #7, respectively, during data communications using SEND(192), RECV(193), or CMND(194).

A503 through A510 contain the completion codes for ports #0 through #7, respectively, following data commu- nications using SEND(192), RECV(193), or CMND(194).

CIO Area: CPU Bus Unit Area

The CPU Bus Unit Area is allocated to CPU Bus Units according to the unit numbers assigned to them, as shown below. Each Unit is allocated 25 words. The Controller Link Units use 22 of the words allocated to them.

Unit no.	Words		Unit no.	Words
0	1500 to 1524	8		1700 to 1724
1	1525 to 1549	9		1725 to 1749
2	1550 to 1574	10		1750 to 1774
