State Configurable Timer (SCT) Four-channel PWM example
=======================================================
Example description
-------------------
LPC5411x SCT Four-channel PWM program for LPCXpresso board

This example (SCTx_pwm_4ch) demonstrates simple four-channel PWM generation.
It uses the unified 32-bit timer to generate single-edge aligned outputs. Channels can have different polarity.
The demonstration state machine has been configured for positive pulses at SCT_OUT0/1 and negative pulses at SCT_OUT2/3.
SCT_IN0 (coming from SCTIPU and assigned to P2_5 in case of LPC15xx) is used as ABORT input.
If low, it forces the outputs to their idle states, halts the timer, and generates an interrupt.

SCT_OUT0 = P0.7  = PWM1
SCT_OUT1 = P0.8  = PWM2
SCT_OUT2 = P0.9  = PWM3
SCT_OUT3 = P0.10 = PWM4


Special connection requirements
-------------------------------
LPC54114 LPCXpresso board:
Connect 4-Channels of a oscilloscope to all 4 SCT Outputs (P0.7, P0.8, P0.9, and P0.10) to monitor the four PWM channels.
