RX65N Group, RX651 Group 1. Overview Table 1.1Outline of Specifications (3/10)ClassificationModule/FunctionDescription Low power Low power consumption Module stop function consumption function Four low power consumption modes Sleep mode, all-module clock stop mode, software standby mode, and deep software standby mode Battery backup function When the voltage on the VCC pin drops, battery power from the VBATT pin is supplied to keep the real-time clock (RTC) operating. Interrupt Interrupt controller Peripheral function interrupts: 262 sources (ICUB) External interrupts: 16 (pins IRQ0 to IRQ15) Software interrupts: 2 sources Non-maskable interrupts: 7 sources Sixteen levels specifiable for the order of priority Method of interrupt source selection: The interrupt vectors consist of 256 vectors (128 sources are fixed. The remaining 128 vectors are selected from among the other 123 sources.) External bus extension The external address space can be divided into eight areas (CS0 to CS7), each with independent control of access settings. Capacity of each area: 16 Mbytes (CS0 to CS7) A chip-select signal (CS0# to CS7#) can be output for each area. Each area is specifiable as an 8-, 16-, or 32-bit bus space. The data arrangement in each area is selectable as little or big endian (only for data). SDRAM interface connectable Bus format: Separate bus, multiplex bus Wait control Write buffer facility DMA DMA controller 8 channels (DMACAa) Three transfer modes: Normal transfer, repeat transfer, and block transfer Activation sources: Software trigger, external interrupts, and interrupt requests from peripheral functions EXDMA controller 2 channels (EXDMACa) Four transfer modes: Normal transfer, repeat transfer, block transfer, and cluster transfer Single-address transfer enabled with the EDACKn signal Request sources: Software trigger, external DMA requests (EDREQn), and interrupt requests from peripheral functions Data transfer controller Three transfer modes: Normal transfer, repeat transfer, and block transfer (DTCb) Request sources: External interrupts and interrupt requests from peripheral functions Sequence transfer R01DS0276EJ0230 Rev.2.30 Page 4 of 246 Jun 20, 2019 Document Outline Features 1.
