AM625: GPMC_CONFIG1 WAITMONITORINGTIME bit description

Part Number: AM625

Hi,

My customer wants to use GPMC wait pins.
It seems typos in GPMC_CONFIG1 Register in TRM Table 12-2779.
There are "TwoDeviceB4" and "OneDeviceB4" description and it does not make sense.


FYI. AM437x TRM description is like this.

I thinks the wait monitoring feature is exactly the same in both devices, correct?

Thanks and regards,
Koichiro Tashiro
