Low-Level I/O (ZGIO-) Definitions
Simple Tokens and Structured Tokens for Device-Related or
Controller-Related Events
The following tokens are present in all device-related or controller-related events:
ZGIO-TKN-CTL CTL marker. This token marks the beginning of an entry in
the controller table, and it occurs once for each controller.
A controller entry comprises this and the next six defined
tokens (ZGIO-TKN-CTLKILL through ZGIO-TKN-
CTLRACWORD).
ZGIO-TKN-CTLKILL Indicates whether the controller for this CTL entry was
disabled. Values can be:
ZSPI-VAL-TRUE (the controller was disabled)
ZSPI-VAL-FALSE (the controller was not disabled)
ZGIO-TKN-CTLNEXTCTL Controller address of the next controller in the controller
group, if this controller is in a controller group.
ZGIO-TKN-CTLNEXTCHN Channel address of the next controller in the controller
group, if this controller is in a controller group.
ZGIO-TKN-CTLINTFREQ Frequency of interrupts that occur on this controller.
ZGIO-TKN-MAXINTFREQ Maximum frequency of interrupts permitted on this
controller.
ZGIO-TKN-CTLRACWORD Contains a zero value. Not used.
