MSP432E411Y: Is the EPI IRDY signal available as an asynchronous bus WAIT signal?

Sh.Sasaki

Part Number: MSP432E411Y

Hi experts,

Is the EPI IRDY signal available as an asynchronous bus WAIT signal?

TRM only has a time chart for synchronous access to PSRAM using IRDY signals. Is there a timing chart using IRDY on HostBus (asynchronous 16bit bus)?

Best regards,

Hi Sasaki,

1. The iRDY signal can be used on Host-Bus mode the information related to EPI can be found in chapter 16 of the MSP432E4 Technical Reference Manual and host bus mode is found in 16.4.3. Table 16-8 also provides context on the signal connections.

2. There is Figure 16-5 which demonstrates the iRDY access stalls with EPI0S32 and EPI0S31.

Regards,

Luke
