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

•

0001001 = RB9 buffer interrupt

0001000 = RB8 buffer interrupt

0000111 = TRB7 buffer interrupt

0000110 = TRB6 buffer interrupt

0000101 = TRB5 buffer interrupt

0000100 = TRB4 buffer interrupt

0000011 = TRB3 buffer interrupt

0000010 = TRB2 buffer interrupt

0000001 = TRB1 buffer interrupt

0000000 = TRB0 Buffer interrupt

Note 1: The ICODE<6:0> bits are cleared when the corresponding interrupts flag bits in the CiINTF register are

cleared.

2: The ICODE<6:0> bits only reflect the status of enabled interrupt sources. The corresponding bits in the

CiINTE register must be set.
