(5) MaxTokenHoldTimeArray
An8(64bytearrayvariable,inwhicheachsetof2bytesrepresentsthedelegationtime
(setasanoctettime)assignedtoadevice.Thedelegationtimedenotesatimeperiod
that is given to a device by means of a PT message sent from the LAS within each token
circulation cycle.
The unit is in octet time.
Theleading2bytescorrespondtothedeviceaddress0x00,andthenal2bytestothe
device address 0xFF.
Specify the subindex to access this parameter.
(6) BootOperatFunctionalClass
Writing 1 to this parameter in a device and restarting the device causes the device to start
as a basic device.
On the contrary, writing 2 to this parameter and restarting the device causes the device to
start as an LM.
(7) CurrentLinkSettingRecord/ConguredLinkSettingsRecord
CurrentLinkSettingRecord indicates the bus parameter currently used.
Ontheotherhand,ConguredLinkSettingsRecordindicatesthebusparametertobeused
when the device becomes the LAS.
If the device is LAS, both parameters have the same value.
