Enumerated value used on its own in if condition

[jotego]

SRMC_RES is defined as:

fx68k/fx68k.sv

Line 2305 in 0602ee4

enum int unsigned { SRESET = 0, SIDLE, S0, S2, S4, S6, SRMC_RES} busPhase, next;

So it must have a value of 6 and at least 3 bits. Then it is used in this if condition:

fx68k/fx68k.sv

Line 2397 in 0602ee4

else if( Clks.enPhi2 & bcComplete & ~SRMC_RES)

What is the meaning of that? Clks.enPhi2 and bcComplete are single bits, the SRMC_RES is, well, 32 bit as an integer with a value of 6. What is the meaning of having it in the expression?

[jotego]

If SRMC_RES is 6, the ~SRMC_RES should be 1 in the LSB. But what's the point of having it there? It must be a leftover.

Yes, it's a typo, the ~SRMC_RES operand shouldn't be there at all. But it is harmless because the value doesn't alter the condition.
