DMA interrupt enable 2

Number	TBRegisterNumber::$CE
Readable	TBRegisterReadable::Yes
Writable	TBRegisterWritable::Yes
Short Description	ShortDesc::UART Interrupts that can override DMA

 bit 7 = Reserved must be zero
 bit 6 = UART1 Tx empty
 bit 5 = UART1 Rx half full     \ shared
 bit 4 = UART1 Rx available     / interrupt
 bit 3 = Reserved must be zero
 bit 2 = UART0 Tx empty
 bit 1 = UART0 Rx half full     \ shared
 bit 0 = UART0 Rx available     / interrupt

• Set bits indicate the corresponding interrupt will interrupt a dma operation when in hw im2 mode

soft reset = 0x00
