TIOR2A is initialized to H'00 by a power-on reset, and in hardware standby mode and software
standby mode.
Bit 7—Reserved: This bit is always read as 0, and should only be written with 0.
Bits 6 to 4—I/O Control 1B2 to 1B0, 1D2 to 1D0, 1F2 to 1F0, 2B2 to 2B0 (IO1B2 to IO1B0,
IO1D2 to IO1D0, IOF12 to IO1F0, IO2B2 to IO2B0): These bits select the general register
(GR) function.
Bit 3—Reserved: This bit is always read as 0, and should only be written with 0.
Bits 2 to 0—I/O Control 1A2 to 1A0, 1C2 to 1C0, 1E2 to 1E0, 2A2 to 2A0 (IO1A2 to IO1A0,
IO1C2 to IO1C0, IO1E2 to IO1E0, IO2A2 to IO2A0): These bits select the general register
(GR) function.
