32 bit bus in multiplexed mode

[immanuelraja]

Hi, I am using TWR-K60F120M tower , I want to configure 32 bit bus in multiplexed mode. Please suggest the Register   configuration (The board is working fine in 16 bit non multiplexed mode).

Hi, Immanuel,

If you use 32 bits multiplexed mode, from hardware perspective, you have to use 32 bits latch device to latch the address in the address stage of FlexBus timing.

From software perspective, you have to set the port size bits FB_CSCRn[ps]=00 in binary, and set the FB_CSPMCR register if you use byte enbale signals.

Hope it can help you
