After rewriting historical past with their discovery of a Nazi U-boat off the coast of latest Jersey, mythical divers John Chatterton and Richie Kohler determined to enquire the nice enduring secret of history's so much infamous shipwreck: Why did big sink as quick because it did?

To resolution the query, Chatterton and Kohler gather a workforce of specialists to discover substantial, research its engineering, and dive to the ruin of its sister send, Brittanic, the place Titanic's final secrets and techniques could be revealed.

Titanic's final secrets and techniques is a rollercoaster journey in the course of the shipbuilding heritage, the transatlantic luxurious liner company, and shipwreck forensics. Chatterton and Kohler weave their means via a labyrinth of clues to find that big used to be now not the powerful, heroic send the area proposal she used to be and that the lads who outfitted her coated up her flaws while catastrophe struck. If vast had remained afloat for simply hours longer than she did, greater than thousand humans may have lived rather than died, and the parable of the good send will be certainly one of rescue rather than tragedy.

Titanic's final secrets and techniques is the never-before-told tale of the send of desires, a modern experience that solves a ancient secret.

Example text

Clearing the MODF bit is accomplished by reading the SPSR (with MODF set), followed by a write to the SPCR. Control bits SPE and MSTR may be restored by user software to their original state after the MODF bit has been cleared. It is also necessary to restore DDRD after a mode fault. Bits 3-0 — Not Implemented These bits always read zero. 3 Serial Peripheral Data l/O Register (SPDR) The serial peripheral data l/O register is used to transmit and receive data on the serial bus. Only a write to this register will initiate transmission/reception of another byte, and this will only occur in the master device.

RCKB is zero and cannot be set while in normal operating modes. The diagram shown in Figure 5-7 and the data given in Table 5-3 and Table 5-4 illustrate the divider chain used to obtain the baud rate clock. Note that there is a fixed rate divide-by-16 between the receive clock (RT) and the transmit clock (Tx). The actual divider chain is controlled by the combined SCP[1:0] and SCR[2:0] bits in the baud rate register as illustrated. 907 K Baud 4800 Baud 4430 Baud *The clock in the “Clock Divided By” column is the internal processor clock MOTOROLA 5-12 SERIAL COMMUNICATIONS INTERFACE MC68HC11A8 TECHNICAL DATA NOTE The divided frequencies shown in Table 5-3 represent baud rates which are the highest transmit baud rate (Tx) that can be obtained by a specific crystal frequency and only using the prescaler division.
