Under available sources, users will see some familiar features: the low frequency internal oscillator, very much like the VLO found in the 2xx and 5xx families; an internal high frequency oscillator, again, akin to the DCO that users would find in other 2xx, 4xx, and 5xx families. This high frequency oscillator is different in that it is defined for a much more specific frequency range. The external sources, CLKIN, is like the XT1 found in other MSP430s and can support both low and high frequency crystals. The other JTAG clock input, TDI, is, again, a common JTAG clock interface that is found in the traditional MSP430s. The systems clocks, again, are in-line with most of the MSP430 families with an MCLK, or main clock, SMCLK, meaning sub-main clock, and an ACLK, or auxiliary clock. The L092 does provide an additional system clock called the VLOCLK. This is a very distinct difference because this clock is directly sourced from the internal low frequency oscillator and is always on. So please note when this presentation refers to power numbers, especially with LPM3 and LPM4, these numbers are representative of this active clock, which is a departure from TI’s traditional operation of LPM3 and LPM4.
