27  *  controller 2: channels 4-7, word operations, ports C0-DF
32  *  - channels 5-7 are word - addresses/counts are for physical words
33  *  - transfers must not cross physical 64K (0-3) or 128K (5-7) boundaries
36  *  - page registers for 5-7 don't use data bit 0, represent 128K pages
37  *  - page registers for 0-3 use bit 0, represent 64K pages
52  *  Address mapping for channels 5-7:
61  * Again, channels 5-7 transfer _physical_ words (16 bits), so addresses
65  * Transfer count (_not # bytes_) is limited to 64K, represented as actual
66  * count - 1 : 64K => 0xFFFF, 1 => 0x0000.  Thus, count is always 1 or more,
67  * and up to 128K bytes may be transferred on channels 5-7 in one operation.
