Understanding filter and mask of MCP2515

All of your masks and filters are set to accept addresses containing:
0b XXX1 0000 XXXX XXXX XXXX XXXX XXXX XXXX (0x10000000)

SEND3 has this address:
0b XXX0 0000 1111 1111 0111 0111 0000 0000 (0x00FF7700)
That does not match because the 29th bit is 0 and the filter requires the 29th bit to be 1.
