MASK DATA: The bits to be traced are specified by a hexadecimalnumber (2 digits).For example, to trace the signals at bit 7,6,5 and 0, set E1(hexadecimal) to MASK DATA.#7 #6 #5 #4 #3 #2 #1 #0E1% 1 1 1 0 0 0 0 1However, even if bit 4,3,2 and 1 changes, tracing (memoryregistration) cannot be done but signal status is memorized when atracing is executed.[Correspondence of binary and hexadecimal number]0000 2 : 0 16 0001 2 : 1 16 0010 2 : 2 16 0011 2 : 3 160100 2 : 4 16 0101 2 : 5 16 0110 2 : 6 16 0111 2 : 7 161000 2 : 8 16 1001 2 : 9 16 1010 2 : A 16 1011 2 : B 161100 2 : C 16 1101 2 : D 16 1110 2 : E 16 1111 2 : F 16225
