LPC2939
ARM9 microcontroller with CAN, LIN, and USB
6.15.7.1
Pin description
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
shows the QEI pins.
Table 26.
Symbol
QEI0 IDX
QEI0 PHA
6.15.7.2
Clock description
The QEI module is clocked by CLK_MSCSS_QEI, see
Section 6.7.2
. The frequency of
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.
6.16 Power, Clock and Reset control SubSystem (PCRSS)
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).
Figure 11
provides an overview of the PCRSS. An AHB-to-DTL bridge controls the
communication with the AHB system bus.
