Bit Name value R/W Description
15 to 8 —
All 1 R/W Reserved
These bits are always read as 1, and the write value
should always be 1.

SIOFUP1 1
R/W Controls pull-up of the MODE6/SIOF_MCLK pin
0: MODE6/SIOF_ MCLK pull-up off
1: MODE6/SIOF_ MCLK pull-up on*
6
SIOFUP0 1
R/W Controls pull-up of the MODE5/SIOF_SYNC pin
0: MODE5/SIOF_SYNC pull-up off
1: MODE5/SIOF_SYNC pull-up on*
5
CLKPUP 1
R/W Controls pull-up of the SCIF2_RXD/SIOF_RXD pin
0: SCIF2_RXD/SIOF_RXD pull-up off
1: SCIF2_RXD/SIOF_RXD pull-up on
4
NMIPUP 1
R/W Controls pull-up of the NMI pin
0: NMI pull-up off
1: NMI pull-up on
3
IRL3PUP 1
R/W Controls pull-up of the IRL3 pin
0: IRL3 pull-up off
1: IRL3 pull-up on
2
IRL2PUP 1
R/W Controls pull-up of the IRL2 pin
0: IRL2 pull-up off

1: IRL0 pull-up on
Note: * The pull-up MOS of this pin cannot be used for MODE pin setting during power-on reset
by the PRESET pin. (The pull-up MOS is turned off during power-on reset by the
PRESET pin.)
