(KMPCR), and registers (TCR_X/TCR_Y, TCSR_X/TCSR_Y,
TICRR/TCORA_Y, TICRF/TCORB_Y, TCNT_X/TCNT_Y,
TCORC, TCORA_X, TCORB_X, TCONRI, and TCONRS) of
8-bit timers (TMR_X and TMR_Y)

in areas from H'(FF)FFF0 to H'(FF)FFF7 and from
H'(FF)FFFC to H'(FF)FFFF
1: Enables CPU access for the keyboard matrix interrupt
registers and input pull-up MOS control register in areas
from H'(FF)FFF0 to H'(FF)FFF7 and from H'(FF)FFFC to
H'(FF)FFFF
When the RELOCATE bit is set to 1, this bit is disabled.
