While taking the SBC Test, a question arose.
When I set the SBC as shown below and stopped WD Refresh, I expected that only FS0B would drop to Low, but both FS0B and RSTB dropped to Low.
Can you tell me what causes RSTB to drop to low?
(For reference, in the settings below
When changing from SBC_FS26_FS_WD_FS_REACTION_FS0B to SBC_FS26_FS_WD_FS_REACTION_NO_EFFECT, RSTB does not drop to Low.)
