Freescale Semiconductor
Hardware Configuration and Boot
2.6 Board Controls and Indicators
This section acquaints you with operational features of the MSC711xADS.
2.6.1
Abort and Reset Control
Table 2-8 describes the MSC711xADS abort and reset features.
2.6.2
MSC711xADS Voltage Measurement
Table 2-9 describes MSC711xADS voltage measurement.
CAUTION:
The job of removing JS5, JS8, and JS6 and soldering the current meter
connections instead is very delicate and should be done by a skilled technician. If
this process is done by unskilled hands or repeated more than 3 times, permanent
damage may occur to the MSC711xADS.

Switch
Name
Description
SW1
MSC711x abort (NMI)
Aborts program execution by issuing a level 0 interrupt to the MSC711x.
The ABORT switch signal is debounced
SW2
MSC711x hard reset
Generates a hard reset to the MSC711x but does not affect the host.
The hard reset signal is debounced.
SW3
Power-on reset
Performs a power-on reset to the MPC8272 and to the MSC711x; all
configuration and all data residing in volatile memories are lost.
SW10
MPC8272 soft reset
Generates a soft reset to the MPC8272. The soft reset switch signal is
debounced.
SW11
MPC8272 hard reset
Generates a hard reset to the MPC8272. A hard reset to the MPC8272
also generates a hard reset to the MSC711x if JP6 is configured
accordingly (see Section 2.4.13, MPC8272 Hard Reset to MSC711x
Hard Reset (JP6), on page 17). The HRESET switch signal is
debounced.
SW12
MPC8272 abort (NMI)
Aborts program execution by issuing a level 0 interrupt to the MPC8272.
The ABORT switch signal is debounced.

Description
JS5
Core voltage measurement
JS5 resides in MSC711x main core current flow. To measure core
current, JS5 should be removed with a solder tool and a current meter
should be connected instead with wires as short and thick as possible.
JS8
MSC711x I/O voltage
measurement
JS8 resides in the MSC711x main I/O current flow. To measure I/O
current, JS8 should be removed with a solder tool, and a current meter
should be connected, with wires as short and thick as possible.
JS6
MSC711x PLL voltage
measurement
JS6 resides in MSC711x main PLL current flow. To measure PLL
current, JS6 should be removed with a solder tool, and a current meter
should be connected instead, with wires as short and thick as possible.
