Differences between NXP industrial UARTs* and NXP SC16CxxxB devices

* Note: UART products falling into industrial category: 1 Industrial temperature at commercial price 2 Synchronous use requires a clock from host SCCxxx, SC28xxx, SC26xxx, SC28Lxxx 3 FIFO depth varies depending on UART 4 Clock is shut off but register contents remain
