9.1.19 Control Peripherals
The devices support the following peripherals that are used for embedded control and communication:
ePWM:
The enhanced PWM peripheral supports independent/complementary PWM generation, adjustable dead-
band generation for leading/trailing edges, latched/cycle-by-cycle trip mechanism. Some of the PWM pins
support the HRPWM high resolution duty and period features. The type 1 module found on 2802x devices
also supports increased dead-band resolution, enhanced SOC and interrupt generation, and advanced
triggering including trip functions based on comparator outputs.
eCAP:
The enhanced capture peripheral uses a 32-bit time base and registers up to four programmable events in
continuous/one-shot capture modes.
This peripheral can also be configured to generate an auxiliary PWM signal.
ADC:
The ADC block is a 12-bit converter. It has up to 13 single-ended channels pinned out, depending on the
device. It contains two sample-and-hold units for simultaneous sampling.
Comparator:
Each comparator block consists of one analog comparator along with an internal 10-bit reference for
supplying one input of the comparator.
9.1.20 串行端口外设
此器件支持下列的串行通信外设：
SPI：
SPI 是一个高速同步串行I/O 端口，此端口允许编程长度（1 至16 位）的串行位流以可编程的位传输速率移入
和移出器件。通常，SPI 用于MCU 和外部外设或者其他处理器之间的通信。典型应用包括外部I/O 或者通过诸
如移位寄存器、显示驱动器和ADC 等器件进行外设扩展。多器件通信由SPI 的主/从操作支持。SPI 包含用于
减少中断服务开销的4 级接收和发送FIFO。
SCI：
I2C：
串行通信接口是一种双线制异步串行端口，通常称为UART。SCI 包含用于减少中断服务开销的4 级接收和发
送FIFO。
内部集成电路(I2C) 模块在MCU 与符合Philips Semiconductors 内部集成电路总线（I2C 总线®）规范版本2.1
并通过I2C 总线连接的其他器件之间提供一个接口。该双线串行总线上连接的外部元件可以通过I2C 模块向
MCU 发送/从MCU 接收多达8 位数据。I2C 包含用于减少中断服务开销的4 级接收和发送FIFO。
