The Primary Output is the source for “Previous Digital PSoC Block” or “Digital Block 03,” selections for the “Clock
Source Select” in the Digital Basic Type A/Communications Type A Block xx Input Register (Table 48 on page 51).
A digital PSoC block may have 0, 1, or 2 outputs depending on its function, as shown in the following table:
