If the CSIB interface is used with handshake, the flash programmer’s HS signal
is connected to a certain V850 port. The port used as the handshake port is
given in Table 6-2.
Flash memory programming off-board requires a dedicated program adapter.
UARTA0, CSIB0 or N-Wire is used as the interface between the flash
programmer and the microcontroller. Flash memory programming off-board
requires a dedicated program adapter (FA series).
The communication between the flash programmer and the microcontroller
utilizes the Asynchronous Serial Interface UARTA0 or optionally the
synchronous serial interface CSIB0.
For programming via the synchronous serial interface CSIB0 without
handshake and with handshake modes are supported. In the latter mode the
port pin P84 is used for the programmer’s handshake signal HS.
