The RESET_REQ# signal enables the CPU to trigger a reset itself via software or in the event of an error (watchdog, security 

violation, etc.). 
The signals RESET_REQ# and RESET_1V8# are connected via DIP switch S1, slot 2. This enables to separate the connection 

between the two signals. Thus an endless boot loop can be prevented in case of a missing RCW. This is necessary to install a new 

RCW. See also section 4.4. 
A diode is connected between RESET_REQ# and DIP switch. This prevents RCW_SRC from being pulled low during the reset 

phase, thus loading the hard-coded RCW (see section 4.4)

Boot-Mode configuration 

The boot behaviour of the LS1012A is determined by a 512-bit Reset Configuration Word (RCW). This is loaded during normal 

operation from the connected QSPI flash memory on the TQMLS1012AL. The processor only supports this one boot source. 
In case the RCW on the QSPI flash is missing or damaged, a fallback mode exists to store a suitable boot configuration in the 

memory. For this purpose a fixed standard configuration of the RCW (Hard-Coded RCW) is loaded, which provides the minimum 

necessary values for the CPU to operate. This is activated via a boot strap resistor at RESET_REQ#. 
By connecting the RESET_REQ# / RCW_SRC signal to DIP switch (S1) (see also section 4.5.1), the value assigned to cfg_rcw_src 
determines one of the two possible RCW sources. The value is read in during Power-On-Reset and can be read out in CPU register 

PORSR1[RCW_SRC]. For this purpose there is a pull-down resistor at the RESET_REQ# signal to select the Hard-Coded RCW during 

the boot process (see following table).

Attention: Missing RCW in QSPI flash 

 

If no RCW is detected in the QSPI flash, the CPU automatically triggers a reset. See section 4.3.
