Normally, 80 * the block for port 0 is at offset 0x0 and the block for port 1 is 81 * at offset 0x80 (i.e. the next page over).

However instead of ordering them like this: 85 * TX sync 1 / TX sync 2 / TX async 1 / TX async 2 86 * SysKonnect has instead ordered them like this: 87 * TX sync 1 / TX async 1 / TX sync 2 / TX async 2 88 * This means that when referencing the TX BMU and RAMbuffer registers, 89 * we have to double the block offset (0x80 * 2) in order to reach the 90 * second queue. This prevents us from using the same formula 91 * (sk_port * 0x80) to compute the offsets for all of the port-specific 92 * blocks: we need an extra offset for the BMU and RAMbuffer registers. 93 * The simplest thing is to provide an extra argument to these macros: 94 * the 'skip' parameter. The 'skip' value is the number of extra pages 95 * for skip when computing the port0/port1 offsets.
