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 15-13 Unimplemented: Read as ‘0’
bit 12-8 FSIZE<4:0>: FIFO Size bits
(1)
11111 = FIFO is 32 messages deep
...
00010 = FIFO is 3 messages deep
00001 = FIFO is 2 messages deep
00000 = FIFO is 1 message deep
bit 7-0 Unimplemented: Read as ‘0’
Note 1: These bits can only be modified in Configuration mode (OPMOD<2:0> = 100).
