30 / 84 page ![]() 2006-01-27 92FD54AI-30 TMP92FD54AI (2) Mode settings Before on-board programming can be performed, the device must be started up in Single Boot Mode. The input pins must be set as follows in order to start the device up in Single Boot Mode. AM0 = 1 AM1 = 1 TEST0 = 0 TEST1 = 0 RESET = 0 → 1 Set the RESET input pin Low (= 0) and set the AM0, AM1, TEST0 and TEST1 pins as shown above. Then de-assert RESET (i.e. set it to 1). The device will start up in Single Boot Mode. (3) Memory map Figure 4.3.2 compares the memory maps for Single-Chip Mode and Single-Boot Mode. As shown, in Single-Boot Mode the internal flash memory is mapped into 010000H to 08FFFFH. The boot ROM (mask ROM) is mapped into FFF400H to FFFFFFH. Figure 4.3.2 Memory maps for Single-Chip Mode and Single-Boot Mode Single-Chip Mode Single-Boot Mode 000000H 000400H 008400H F80000H FFFF00H FFFFFFH FFF000H 000000H 000400H 010000H 090000H FFF400H FFFF00H FFFFFFH 008400H (予約) 内蔵 Flash ROM Internal I/O Internal RAM 32KB External Memory Internal Flash ROM 512KB Internal I/O Internal RAM 32KB External Memory External Memory Reserved Internal Boot ROM 3KB Internal Flash ROM 512KB (Interrupt vector 256B) (Interrupt vector 256B) |
