Flags against other reads, timer 2 at the system clock, target 0010h, reset, after
20000 cycles: the counter read 8 times, then the mode twice; the target read, then the
mode; a lw of the mode, then lhu; lbu of mode+1, then lhu:
 counter reads then mode 0C08 0C08; target read then mode 0C08; lw 0C040C08 then 0408
 lbu mode+1 0C then 0C08; lbu mode 08 then 0408
Target FFFFh with reset (mode 0008h): both flags at once? Reads 70000 cycles in:
 reset at target: 1C08 then 0408; no reset: 1C00 then 0400
Done.
