LPC2921/2923/2925
ARM9 microcontroller with CAN, LIN, and USB
6.14.7.1
Pin description
The QEI module in the MSCSS has the following pins. These are combined with other
functions on the port pins of the LPC2921/2923/2925.
Table 23
shows the QEI pins.
Table 23.
Symbol
QEI0 PHA
Remark:
The index function for the QEI is not pinned out on the LPC2921/2923/2925.
6.14.7.2
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.
6.15 Power, Clock, and Reset control SubSystem (PCRSS)
The Power, Clock, and Reset control SubSystem (PCRSS) in the LPC2921/2923/2925
includes a Clock Generator Unit (CGU), a Reset Generator Unit (RGU) and a Power
Management Unit (PMU).
Figure 8
provides an overview of the PCRSS. An AHB-to-DTL bridge controls the
communication with the AHB system bus.
