Setting these bits to ‘00000000’ specifies the highest frequency of the SQI clock.
bit 7-2 Unimplemented: Read as ‘0’
bit 1 STABLE: T
SQI Clock Stable Select bit
This bit is set to ‘1’ when the SQI clock, T
SQI, is stable after writing a ‘1’ to the EN bit.
1 = T
SQI clock is stable
0 = T
SQI clock is not stable
bit 0 EN: T
SQI Clock Enable Select bit
When clock oscillation is stable, the SQI module will set the STABLE bit to ‘1’.
1 = Enable the SQI clock (T
SQI) (when clock oscillation is stable, the SQI module sets the STABLE bit to ‘1’)
0 = Disable the SQI clock (T
SQI) (the SQI module should stop its clock to enter a low power state); SFRs
can still be accessed, as they use PBCLK5
Note 1: Refer to Table in Section 44.0 “Electrical Characteristics” for the maximum clock frequency specifica-
tions.
