k64 datasheet学习笔记3---Chip Configuration之Times
1.前言
对定时器相关的芯片配置做一概述
2.PDB配置
2.1 PDB介绍
PDB输出触发:
PDB输入触发连接:
2.2 PDB模块交互
2.3 back-to-back确认连接
In this MCU, PDB back-to-back operation acknowledgment connections are implemented as follows:
• PDB channel 0 pre-trigger 0 acknowledgement input: ADC1SC1B_COCO
• PDB channel 0 pre-trigger 1 acknowledgement input: ADC0SC1A_COCO
• PDB channel 1 pre-trigger 0 acknowledgement input: ADC0SC1B_COCO
• PDB channel 1 pre-trigger 1 acknowledgement input: ADC1SC1A_COCO
2.4 PDB间隔触发连接到DAC
2.5 DAC外部触发输入连接
TODO
2.6 脉冲输出连接
PDB脉冲输出信号被链接到CMP模块用作采样窗口?
2.7 脉冲输出使能寄存器实现
3. FlexTimer配置
TODO
4. PIT配置
4.1 PIT/DMA周期触发指定
注:只有DMA通道0~DMA通道3可以通过PIT触发
4.2 PIT/ADC触发
可以通过配置SIM_SOPT7[ADCxTRGSEL] 来决定由哪个PIT触发源触发ADC转换
5. Low-power timer 配置
