Detailed Description
Base APB transaction.
The transaction is used by both apb_driver and apb_monitor. For the driver, the transaction type works for request and response.
Implements the basic transaction attributes (address, data, read/write control). More advanced attributes (e.g. error injection, byte enables, etc.) are not supported.
