About This Manual
This manual describes the modules and peripherals of the MSP430FR58xx, MSP430FR59xx, and
MSP430FR6xx family of devices. Each description presents the module or peripheral in a general sense.
Not all features and functions of all modules or peripherals may be present on all devices. In addition,
modules or peripherals may differ in their exact implementation between device families, or may not be
fully implemented on an individual device or device family.
Pin functions, internal signal connections, and operational parameters differ from device to device. Consult
the device-specific data sheet for these details.
