USER’S MANUAL
The following information is a concise reference only. MC68332 system reset is a com-
plex operation. To understand operation during and after reset, refer to SECTION 4
SYSTEM INTEGRATION MODULE, paragraph 4.6 Reset for more complete discus-
sion of the reset function.
The logic states of certain data bus pins during reset determine SIM operating config-
uration. In addition, the state of the MODCLK pin determines system clock source and
the state of the BKPT pin determines what happens during subsequent breakpoint as-
sertions. Table 3-6 is a summary of reset mode selection options.
