The HC_CONTROL_PIO_MODE bit was introduced in the HC_CONTROL register starting from version 1.1. Therefore, checking the HC_CONTROL_PIO_MODE bit on hardware that adheres to older specification revisions (i.e., versions earlier than 1.1) is incorrect. To address this, add an additional check to read the HCI version before attempting to read the HC_CONTROL_PIO_MODE status.
