4. Examples of Pin Handling for Connecting the E8a
4.3 R32C/160 and R32C/161
4.3.1 Examples of pin handling for connecting the E8a (whole connection)
The following show examples of pin handling for connecting the E8a. When using the E8a as a programmer, the connection
specification between the E8a and the MCUs is the same as shown below.
- Single-chip mode:
See Figure 4.17.
- Memory expansion mode:
See Figure 4.18.
