3.10.3.4 LCD clock source
The following table shows the LCD clock and the corresponding chip clock source.
3.10.3.5 Segment LCD Interrupts
The Segment LCD has multiple interrupt sources. However, all of these sources are OR'd
together to generate a single interrupt request. Read the LFDSR and LGCR registers to
determine the cause of the interrupt.

Default clock (external crystal or reference clock)
Alternate clock
Module clock
K30 Sub-Family Reference Manual, Rev. 6, Nov 2011
Table 3-76. LCD clock source
Default clock is either the system OSC output clock
(OSCOUTCLK) or RTC OSC output clock (RTCOUTCLK).
This is selected by SOPT1[OSC32KSEL] bit in SIM module.
The clock defaults to 32 kHz.
Alternate clock is the MCGIRCLK output that is either the 32
kHz or 2 MHz internal reference clocks. This option is
selected by the user in the MCG module. The clock defaults
to 32 kHz.
