peripherals
Peripherals that are connected to the CPU through a data, address, and controls bus can be handled easily with
instructions for memory manipulation.
oscillator and system clock
Two clocks are used in the system: the system (master) clock (MCLK) and the auxiliary clock (ACLK). The MCLK
is a multiple of the ACLK. The ACLK runs with the crystal oscillator frequency. The special design of the oscillator
supports the feature of low current consumption and the use of a 32 768 Hz crystal. The crystal is connected
across two terminals without any other external components required.
The oscillator starts after applying VCC, due to a reset of the control bit (OscOff) in the status register (SR). It
can be stopped by setting the OscOff bit to a 1. The enabled clock signals ACLK, ACLK/2, ACLK/4, or MCLK
are accessible for use by external devices at output terminal XBUF.
The controller system clocks have to deal with different requirements according to the application and system
condition. Requirements include:
D High frequency in order to react quickly to system hardware requests or events
D Low frequency in order to minimize current consumption, EMI, etc.
D Stable frequency for timer applications e.g., real-time clock (RTC)
D Enable start-stop operation with minimum delay to operation function
These requirements cannot all be met with fast frequency high-Q crystals or with RC-type low-Q oscillators. This
compromise and selected for the MSP430, uses a low-crystal frequency, which is multiplied to achieve the
desired nominal operating range:
