Appendix
D. List of Mode Control Pins and Schematic Diagram of External Cicuits
Table D.1 shows the list of mode control pins of this LSI.
Table D.1 Mode Control Pins
Pin Name
Function
I/O
Description
MD0, MD1, and MD2 Mode control Input
pins 0,1 and 2
Selects the clock-operating mode at a
power-on reset.
MD3 and MD4
Mode control
pins 3 and 4
Input
Selects the bus width and MPX interface of
area 0 at a power-on reset
MD5
Mode control pin Input
5
Selects the endian at a power-on reset
MD6
Mode control pin Input
6
Selects the PCI operating mode at a power-
on reset.
MD8
Mode control pin Input
8
Selects whether to use the crystal resonator
at a power-on reset.
MD10
Mode control pin Input
10
Selects the external CPU at a power-on
reset
MPMD
Chip mode
control pin
Input
Selects either emulation support mode or
LSI operation mode at a power-on reset.
The state of the mode control pins of this LSI is sampled white a power-on reset is applied.
Therefore, these pins can serve as other functions in the other periods.
The method for switching between the control functions and other functions should be examined
referring to figure D.1. See section 40, General Purpose I/O (GPIO), or the relevant sections of the
applicable modules for whether the pins of the other functions are the input, output, or
input/output pins.
