Module kea_hal::system::sim

SIM - System Integration Module

SIM_SCGC - System Clock Gating Control Register

This module controls whether or not a module is connected to the bus clock. This register is controlled by each peripherals respective (software) module.

SIM_BUSDIV

This contains a single bit field that controls whether the bus divider is equal to or half that of the system clock. Because the maximum allowed speed of the bus clock is 20MHz compared to the 40MHz allowed for the system clock, the bus clock divider must be set appropriately if the system clock exceeds 20MHz. By default the system clock is 16MHz.

SIM_SOPT - System Options Register

The SIM holds system configuration options, such as trigger sources, RESET pin usage, etc. All of the options will be implemented in their respective (software) modules. For example reset pin usage is handled by crate::gpio , and the bus divider is handled by crate::clocks.

UUID

the MCU’s 64bit UUID.

SIM_PINSEL - Pin Selection Register

The SIM also holds the Pin Selection Register (SIM_PINSEL) which configures the pins that certain peripherals use for inputs and outputs. This functionality is not controlled by this (software) module, but is instead implemented by their repsective modules. For example SIM_PINSEL[UART0] is handled within the UART (software) module.
