Overview Table 1.4 Event Link Feature Functional description Event Link Controller (ELC) The Event Link Controller (ELC) uses the interrupt requests generated by various peripheral modules as event signals to connect them to different modules, enabling direct interaction between the modules without CPU intervention. See section 16, Event Link Controller in User’s Manual. Table 1.5 Direct memory access Feature Functional description Data Transfer Controller (DTC) A Data Transfer Controller (DTC) module is provided for transferring data when activated by an interrupt request. See section 15, Data Transfer Controller (DTC) in User’s Manual. Table 1.6 Timers Feature Functional description General PWM Timer (GPT) The General PWM Timer (GPT) is a 32-bit timer with 1 channel and a 16-bit timer with 6 channels. PWM waveforms can be generated by controlling the up-counter, down-counter, or the up- and down-counter. In addition, PWM waveforms can be generated for controlling brushless DC motors. The GPT can also be used as a general-purpose timer. See section 20, General PWM Timer (GPT) in User’s Manual. Port Output Enable for GPT (POEG) Use the Port Output Enable for GPT (POEG) function to place the General PWM Timer (GPT) output pins in the output disable state. See section 19, Port Output Enable for GPT (POEG) in User’s Manual. Asynchronous General Purpose Timer (AGT) The Asynchronous General Purpose Timer (AGT) is a 16-bit timer that can be used for pulse output, external pulse width or period measurement, and counting external events. This 16-bit timer consists of a reload register and a down-counter. The reload register and the down-counter are allocated to the same address, and they can be accessed with the AGT register. See section 22, Asynchronous General Purpose Timer (AGT) in User’s Manual. Realtime Clock (RTC) The Realtime Clock (RTC) has two counting modes, calendar count mode and binary count mode, that are controlled by the register settings. For calendar count mode, the RTC has a 100-year calendar from 2000 to 2099 and automatically adjusts dates for leap years. For binary count mode, the RTC counts seconds and retains the information as a serial value. Binary count mode can be used for calendars other than the Gregorian (Western) calendar. See section 23, Realtime Clock (RTC) in User’s Manual. Table 1.7 Communication interfaces (1 of 2) Feature Functional description Serial Communications Interface (SCI) The Serial Communication Interface (SCI) is configurable to five asynchronous and synchronous serial interfaces: Asynchronous interfaces (UART and asynchronous communications interface adapter (ACIA)) 8-bit clock synchronous interface Simple IIC (master-only) Simple SPI Smart card interface. The smart card interface complies with the ISO/IEC 7816-3 standard for electronic signals and transmission protocol. SCI0 has FIFO buffers to enable continuous and full-duplex communication, and the data transfer speed can be configured independently using an on-chip baud rate generator. See section 27, Serial Communications Interface (SCI) in User’s Manual. Digital Addressable Lighting Interface (DALI) A Digital Addressable Lighting Interface (DALI) module is provided. DALI is an international open lighting control communication protocol that includes dimming control of electronic ballasts and LED lights from different manufacturers. The DALI interface module is designed to allow compliance with international standard IEC62386-101 Edition 1.0/2.0 (DALI 2), that includes software control. See section 28, Digital Addressable Lighting Interface (DALI) in User’s Manual. |
