(Continued)

• Register interlock function : Facilitates coding in assembler.

• Built-in multiplier with instruction-level support

• 32-bit multiplication with sign : 5 cycles

• 16-bit multiplication with sign : 3 cycles

• Interrupt (PC, PS save) : 6 cycles, 16 priority levels

• Harvard architecture allowing program access and data access to be executed simultaneously

• Instruction compatible with FR family

• Internal peripheral functions

• Capacity of internal ROM and ROM type

MASK ROM : 64 Kbytes (MB91266)

FLASH ROM : 128 Kbytes (MB91F267/MB91F267N)

• Capacity of internal RAM : 2 Kbytes (MASK product)/4 Kbytes (FLASH memory product)

• A/D converter (sequential comparison type)

Resolution : 8/10 bits : 4 channels × 1 unit, 7 channels × 1 unit

Conversion time : 1.2 µs (Minimum conversion time system clock at 33 MHz)

1.35 µs (Minimum conversion time system clock at 20 MHz)

• External interrupt input : 8 channels

• Bit search module (for REALOS)

Function for searching the MSB (upper bit) in each word for the first 1-to-0 inverted bit position

• C-CAN 32MSB : 1 channel (loaded in MB91F267N only)

• UART (Full-duplex double buffer) : 2 channels

Selectable parity On/Off

Asynchronous (start-stop synchronized) or clock-synchronous communications selectable

Internal timer for dedicated baud rate (U-TIMER) on each channel

External clock can be used as transfer clock

Error detection function for parity, frame, and overrun errors

• 8/16-bit PPG timer : 8 channels (at 8-bit) / 4 channels (at 16-bit)

• Timing generator

• 16-bit reload timer : 3 channels (with cascade mode, without output of reload timer 0)
