+Description: (RW) Read returns value of the Heartbeat update period.
+ Write to the file changes this period value.
+
+ This period should reflect planned polling interval of device
+ health status. High frequency Heartbeat monitoring wastes CPU cycles
+ but minimizes the customer’s system downtime. Also, if there are
+ large service requests that take some time to complete, high frequency
+ Heartbeat monitoring could result in false reports of unresponsiveness
+ and in those cases, period needs to be increased.
+
+ This parameter is effective only for c3xxx, c62x, dh895xcc devices.
+ 4xxx has this value internally fixed to 200ms.
+
+ Default value is set to 500. Minimal allowed value is 200.
+ All values are expressed in milliseconds.

+ The driver does not monitor for Heartbeat. It is left for a user
