Michael,
I really appreciate your reviewing the code so closely. I considered the outer check in getbcch() to prevent these collisions, e.g the first condition that must be met is if(BC_CHAR_RCVD) { ... } which is set by the ISR and cleared by getbcch(). So the variables, bc_bit_count bc_char bc_char_temp reset_ch are never accessed by getbcch() until a PS2 transmission is complete. Does this make sense? |
