Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 31-24 Unimplemented: Read as ‘0’
bit 23 CHSDIE: Channel Source Done Interrupt Enable bit
1 = Interrupt is enabled
0 = Interrupt is disabled
bit 22 CHSHIE: Channel Source Half Empty Interrupt Enable bit
1 = Interrupt is enabled
0 = Interrupt is disabled
bit 21 CHDDIE: Channel Destination Done Interrupt Enable bit
1 = Interrupt is enabled
0 = Interrupt is disabled
