6.1. Connector Description (View from R8A66597)
Connectors JA1, JA2, JA4 and JA6 provide all bus interface pins of the chip, such as processor bus interface
and DMA interface. Therefore, these pins provide the same pin characteristics of the R8A66597FP such as
electric characteristic, I/O direction, and functions except for the signal with *. Note: All pins on JA5 are
unconnected.
The following table shows the pin number and function correspondences.
