Operating Instructions
This chapter provides operating instructions for using the MPC8272ADS in host-controlled
and stand-alone configurations. This information includes controls and indicators, memory
map details, and software initialization of the board.
4.1
Controls and Indicators
The MPC8272ADS has the following switches and indicators.
4.1.1
Power-On RESET Switch—SW3
The power-on reset switch SW3 performs power-on reset to the MPC8272 as if the power
was re-applied to the ADS. When the MPC8272 is reset that way, all configuration and all
data residing in volatile memories is lost. After PORST signal is negated, the MPC8272
re-acquires the power-on reset and hard-reset configuration data from the hard-reset
configuration source. (Flash | EEPROM | BCSR).
4.1.2
ABORT Switch—SW6
The ABORT switch ends program execution by issuing a level 0 interrupt to the MPC8272.
If the ADS is in standalone mode, the user must provide a means for handling the interrupt,
because the MPC8272ADS does not have a resident debugger. The ABORT switch signal
is debounced and may be disabled by software.
4.1.3
Soft Reset Switch—SW7
The soft reset switch SW3 performs soft reset to the MPC8272 internal modules,
maintaining MPC8272’s configuration (clocks and chip-selects) and SDRAMs’ contents.
The switch signal is debounced and software cannot disable it.
4.1.4
Hard Reset Switches—SW6 & SW7
When BOTH switches SW6 and SW7 are depressed simultaneously, hard reset is generated
to the MPC8272. When the MPC8272 is hard reset, all its configuration is lost except for
