I need a little help understanding why KFZW is not using the usual rl and nmot  in the following code.  The zwkfzw0 becomes zwgru eventually, but what are esst_snm16zuuw, esst_srl12zuuw and the map  SRL12ZUUW? 


FLASH_CODE3:8D68EA                 mov     r12, #1F68h     ; map KFZW
FLASH_CODE3:8D68EE                 mov     r13, #3264h     ;  map SRL12ZUUW ; what is this map doing here, what is it?
FLASH_CODE3:8D68F2                 mov     r14, esst_snm16zuuw ; probably nmot, but why the long name?
FLASH_CODE3:8D68F6                 mov     r15, esst_srl12zuuw   ; must be rl ?
FLASH_CODE3:8D68FA                 calls   0, gkf_ipol_S8
FLASH_CODE3:8D68FE                 movb    zwkfzw0, rl4 ;most raw timing value not only uses KFZW like in me7 FR, but uses SRL12ZUUW too?
