Description
Reserved
These bits are always read as 0, and the write value
should always be 0.
Out of the modules RESET and INTC, selects the one
which uses the pin MRESETOUT/IRQOUT.
0: Selects RESET
1: Selects INTC
Selects the pin group used by the SIOF.
0: Uses the SIOF pin selected by P1MSEL4 and 3.
1: Uses the SIOF pin selected by P1MSEL12, 11, and
Note: At power-on reset by the PRESET pin, MODE5
Out of the modules PCIC and MMCIF, selects the one
which uses the pins REQ3 and GNT3/MMCCLK.
0: PCIC
1: MMCIF
When 1 is selected, the REQ3 pin is determined as
unused pin. Accordingly, set bit 3 (PE3PUPR) of the
port E pull-up control register to B'1.
