Renesas High-Speed Serial I/F (Rhsif) / Multichannel Serial Peripheral Interface (Mspi) - Renesas RH850/U2A 292pin User Manual

RH850/U2A 292pin
6.6 Renesas High-Speed Serial I/F (RHSIF) / Multichannel Serial Peripheral
Interface (MSPI)
The CN5 connector can be used to connect to the device's RHSIF and MSPI0 interface.
Refer to 7.3 RHSIF/MSIP Connector CN5 for the CN5 pin assignment.
RHSIF and MSPI0 interface at CN5 are operated in LVDS mode.
Rx and Tx signals available at CN5 can be swapped by setting the jumper JP1:
•
JP1[2-1]:
−
RXDP/RXDN at CN5 pins 7 and 9
−
TXDP/TXDN at CN5 pins 1 and 3
•
JP1[2-3]:
−
RXDP/RXDN at CN5 pins 1 and 3
−
TXDP/TXDN at CN5 pins 7 and 9
Notes
1. In order to minimize signal interference no signals from CN5 are connected to CN16. If required they can
be connected via 0 Ω resistors R15 to R18 and R21 to R23.
2. Swapping the Rx/Tx signals allows board-to-board communication e.g. with another piggyback board via
separate cables.
