6.15.7.1 Pin description
6.15.7.2 Clock description
6.16 Power, Clock and Reset control SubSystem (PCRSS)
The QEI module in the MSCSS has the following pins. These are combined with other
functions on the port pins of the LPC2939.
Table 26.
The QEI module is clocked by CLK_MSCSS_QEI, see
this clock is identical to CLK_MSCSS_APB since they are derived from the same base
clock BASE_MSCSS_CLK.
If the QEI is not used its CLK_MSCSS_QEI branch clock can be switched off.
The Power, Clock and Reset Control Subsystem in the LPC2939 includes a Clock
Generator Unit (CGU), a Reset Generator Unit (RGU), and a Power Management Unit
(PMU).
