CPG Pin Configuration
CPG Register Configuration
Set to 1 in a power-on reset.
For details of synchronous DRAM self-refreshing, see section 13.3.5, Synchronous
DRAM Interface.
Depends on the clock operating mode set by pins MD2–MD0.

Function
Set clock operating mode
Connects crystal resonator
Connects crystal resonator, or used as
external clock input pin
Selects use/non-use of crystal resonator
When MD8 = 0, external clock is input from
EXTAL
When MD8 = 1, crystal resonator is
connected directly to EXTAL and XTAL
Used as external clock output pin
Level can also be fixed
0 when CKIO output clock is unstable and in
case of synchronous DRAM self-refreshing*
