115 / 923 page ![]() 77 Section 3 Operating Modes 3.1 Operating Modes, Types, and Selection This LSI has five operating modes and three clock modes, determined by the setting of the mode pins (MD3–MD0). Do not change the mode pin settings during LSI operation (while power is on). (In the F-ZTAT version, however, MD1 can be changed in the power-on reset state.) Table 3.1 indicates the setting method for the operating mode. Table 3.1 Operating Mode Setting Mode Pin Setting Mode On-Chip CS0 Area No. FWP MD3* 1 MD2* 1 MD1 MD0 Name ROM 112 Pin 144 Pin 0 1 x x 0 0 MCU mode 0 Not Active 8-bit space 16-bit space 1 1 x x 0 1 MCU mode 1 Not Active 16-bit space 32-bit space 2 1 x x 1 0 MCU mode 2 Active 8/16-bit space* 2 8/16/32-bit space* 2 3 1 x x 1 1 Single chip mode Active — — 4 1 1 1 1 1 PROM mode* 3 Active — — — 0 x x 0 0 Boot mode* 4 Active 8/16-bit space* 2 8/16/32-bit space* 2 — 0 xx0 1 — — — 0 x x 1 0 User programming mode* 4 Active 8/16-bit space* 2 8/16/32-bit space* 2 — 0 xx1 1 — — — 1 1 1 0 1 Flash programmer mode* 4 Active — — Notes: *1 MD2 and MD3 pins select the clock mode in modes 0–3 (table 3.2). *2 Set by BCR2 of BSC. *3 Only ZTAT. *4 Only F-ZTAT. |
