 At the end of the handlers after restoring the context/CSRs, a piece of smart code should be added with following highest to lowest order of priority:
 
-1. if MEPC = lpend0 - 4 and lpcount0 > 1 then MPEC should be set to lpstart0 and lpcount0 should be decremented by 1,

 The 2 last cases are the standard ones when ebreak/ecall are not inside an HWLopp.
