Which versions of the SH77{34|63} manuals did you use?
Several registers are called slightly different in mine, and also in my
r8a7740 manual.

TWBIP is actually two bits in my manual: TWB1IP and TWB0IP

Nonexistent bit in my manual.

Nonexistent bit in my manual.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
