LPC2917/19
ARM9 microcontroller with CAN and LIN
8.7.7.2
Description
See section
Section 8.4.3.2
for a description of the timers.
8.7.7.3
MSCSS timer-pin description
MSCSS timer 0 has no external pins.
MSCSS timer 1 has a PAUSE pin available as external pin. The PAUSE pin is combined
with other functions on the port pins of the LPC2917/19.
Table 22
shows the MSCSS
timer 1 external pin.

Symbol
MSCSS PAUSE
8.7.7.4
MSCSS timer-clock description
The Timer modules in the MSCSS are clocked by CLK_MSCSS_MTMRx (x = 0-1), see
Section 7.2.2
. Note that each timer has its own CLK_MSCSS_MTMRx branch clock for
power management. The frequency of all these clocks is identical to CLK_MSCSS_VPB
since they are derived from the same base clock BASE_MSCSS_CLK.
Note that, unlike the timer modules in the Peripheral SubSystem, the actual timer counter
registers run at the same clock as the VPB system interface CLK_MSCSS_VPB. This
clock is independent of the AHB system clock.
If a timer module is not used its CLK_MSCSS_MTMRx branch clock can be switched off.
8.8 Power, clock and reset control subsystem
8.8.1
Overview
The Power, Clock and Reset Control Subsystem (PCRSS) in the LPC2917/19 includes a
Clock Generator Unit (CGU), a Reset Generator Unit (RGU) and a Power Management
Unit (PMU).
8.8.2
Description
Figure 11
provides an overview of the PCRSS. An AHB-to-DTL bridge takes care of
communication with the AHB system bus.
