Bus Operation
To exit the LPSTOP mode, the processor CLK must be restarted for at least eight CLK and
two BCLK periods prior to asserting either the RSTI or generating an interrupt. It is impera-
tive before asserting RSTI or generating the interrupt no alternate master activity be done
until the processor begins exception processing for either the reset or interrupt. Additionally,
the following control signals must be pulled-up or negated during this time: BB, TRA, TA,
TEA, CLA, BGR, BG, SNOOP, AVEC, MDIS, CDIS, TCI, and TBI. The processor uses the
PSTx encoding of $18 to indicate exception processing.
