a. Applies only ONCE after power-up reset.
When HCW is applied from Flash (SW9/7 is ON) DLLDIS and MODCK_HI bits have value shown in ta-
ble. In case of HCW source will be from BCSR (SW9/7 is OFF) those bits set up manually - DLLDIS is
controlled by JP1 and MODCK_HI - by DIP-switch SW9/4-6.

Manual Soft Reset
To allow run-time Soft-reset, when the Command Converter is disconnected from the JTAG/ONCE
connector and to support resident debuggers, a Soft Reset push-button is provided. When the Soft
Reset push-button is depressed, the SRESET line is asserted to the MSC8101, generating a Soft
Reset sequence.
Since the SRESET line may be driven internally by the MSC8101, it must be driven by an open-
drain gate, to avoid contention over that line. If off-board H/W connected to the MSC8101ADS is
to drive SRESET line, then, it should do so with an open-drain gate, this, to avoid contention over
this line.
