Description

HSPI 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 HSPI request the access to the bus. others: Maximum communication is set to MAXTRAN+1 bytes

0 (B_0x0): Maximum communication disabled
CSBOUND

CS 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: CS boundary set to 2CSBOUND bytes

0 (B_0x0): CS boundary disabled
