LPC2926/2927/2929
ARM9 microcontroller with CAN, LIN, and USB
6.15.6.1
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 LPC2926/2927/2929.
Table 25
shows the
MSCSS timer 1 external pin.

6.15.6.2
Clock description
The timer modules in the MSCSS are clocked by CLK_MSCSS_MTMRx (x = 0 to 1), see
Section 6.7.2
. 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_APB
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 APB system interface CLK_MSCSS_APB. 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.
6.15.7
Quadrature Encoder Interface (QEI)
A quadrature encoder, also known as a 2-channel incremental encoder, converts angular
displacement into two pulse signals. By monitoring both the number of pulses and the
relative phase of the two signals, the user can track the position, direction of rotation, and
velocity. In addition, a third channel, or index signal, can be used to reset the position
counter. The quadrature encoder interface decodes the digital pulses from a quadrature
encoder wheel to integrate position over time and determine direction of rotation. In
addition, the QEI can capture the velocity of the encoder wheel.
The QEI has the following features:
Tracks encoder position.
Increments/decrements depending on direction.
Programmable for 2
×
or 4
×
position counting.
Velocity capture using built-in timer.
Velocity compare function with less than interrupt.
Uses 32-bit registers for position and velocity.
Three position compare registers with interrupts.
Index counter for revolution counting.
Index compare register with interrupts.
Can combine index and position interrupts to produce an interrupt for whole and
partial revolution displacement.
Digital filter with programmable delays for encoder input signals.
Can accept decoded signal inputs (clk and direction).
Connected to APB.
