Signal Name
Description
V
DD
Internal Logic Power
V
DD
dedicated for use with the device core. The voltage should be well-regulated and the input should be
provided with an extremely low impedance path to the V
DD
power rail.
V
DDH
Input/Output Power
This source supplies power for the I/O buffers. The user must provide adequate external decoupling
capacitors.
V
CCSYN
System PLL Power
V
CC
dedicated for use with the system Phase Lock Loop (PLL). The voltage should be well-regulated and
the input should be provided with an extremely low impedance path to the V
CC
power rail.
GND
System Ground
An isolated ground for the internal processing logic and I/O buffers. This connection must be tied externally
to all chip ground connections, except GND
SYN
. The user must provide adequate external decoupling
capacitors.
GND
SYN
System PLL Ground
Ground dedicated for system PLL use. The connection should be provided with an extremely
low-impedance path to ground.

CLKIN
Input
Clock In
Primary clock input to the MSC8113 PLL.
CLKOUT
Output
Clock Out
The bus clock.
Reserved
Input
Pull down.
Table 3-4. Reset and Configuration Signals
Signal Name
Type
Signal Description
PORESET
Input
Power-On Reset
When asserted, this line causes the MSC8113 to enter power-on reset state.
RSTCONF
Input
Reset Configuration
Used during reset configuration sequence of the chip. A detailed explanation of its function is
provided in the MSC8113 Reference Manual. This signal is sampled upon deassertion of
PORESET.
Note:
When PORESET is deasserted, the MSC8113 also samples the following signals:
• BM[0–2]—Selects the boot mode.
• MODCK[1–2]—Selects the clock configuration.
• SWTE—Enables the software watchdog timer.
• DSISYNC, DSI64, CNFGS, and CHIP_ID[0–3]—Configures the DSI.
Refer to Table 3-5 for details on these signals.
