Port Pi direction register (i = 0 to 7, 9, 10) (Notes 1, 2)
b7 b6 b5 b4 b3 b2
Note 1: Make sure the PD7 and PD9 registers are written to by the next instruction after setting the PRCR
register's PRC2 bit to "1" (write enabled).
Note 2: During memory expansion and microprocessor modes, the PD register for the pins functioning
as bus control pins (A
HOLD, HLDA and BCLK) cannot be modified.
