(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 final 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/ConfiguredLinkSettingsRecord
CurrentLinkSettingRecord indicates the bus parameter currently used.
On the other hand, ConfiguredLinkSettingsRecord indicates the bus parameter to be used
when the device becomes the LAS.
If the device is LAS, both parameters have the same value.
