R/W Description
R Reserved
These bits are always read as 0. The write value should
always be 0.
R/W PA25 Mode
This bit selects the function of the HIFMD/PA25/A25 pin.
This pin functions as HIFMD (HIF) only during a power-on
reset that is output from the RES pin.
0: PA25 I/O (port)
1: A25 output (BSC)
R Reserved
This bit is always read as 0. The write value should always
be 0.
R/W PA24 Mode
This bit selects the function of the PA24/A24 pin.
0: PA24 I/O (port)
1: A24 output (BSC)
