Description

XSPI device configuration register 3

Fields

MAXTRAN

Maximum transfer This field enables the communication regulation feature. The NCS is released every MAXTRAN+1 clock cycles when the other XSPI request the access to the bus. Others: maximum communication is set to MAXTRAN + 1 bytes.

0 (B_0x0): maximum communication disabled
CSBOUND

NCS boundary This field enables the transaction boundary feature. When active, a minimum value of 3 is recommended. The NCS is released on each boundary of 2CSBOUND bytes. Others: NCS boundary set to 2CSBOUND bytes
