38 / 224 page  TMP93CS44/S45 2004-02-10 93CS44-36 Setting to reset/interrupt vector 1. Reset vector The vector base addresses are depended on the products. Type Number Vector Base Address PC Setting Sequence after Reset Notes TMP93CS44 TMP93CS45 TMP93PS44 TMP93CU44 TMP93CW44 TMP93PW44A FFFF00H PC<7:0> ← Address FFFF00H PC<15:8> ← Address FFFF01H PC<23:16> ← Address FFFF02H P27 to P20/A23 to A16 pins input ports with pull-up due to reset. The logic data is “FFH”. When port 2 is used as A23 to A16 pins to access the program ROM, set PC<23:16> to “FFH” and the reset vector to “FF0000H to FFFFFFH” (for mainly products without ROM). 2. Interrupt vector (except reset vector) PC<7:0> PC<15:8> PC<23:16> XX FFFF00H FFFF01H FFFF02H FFFF03H PC<7:0> PC<15:8> PC<23:16> XX +0 +1 +2 +3 XX: Don’t care Address refer to vector |
