Features
Overview
The Reduced Power Stage Controller is a high performance waveform controller.

Many register and bit references in this section are written in general form.
The purpose of a Power Stage Controller (PSC) is to control power modules on a board. It has two outputs
.
These outputs can be used in various ways:
The PSCR has two inputs the purpose of which is to provide means to act directly on the generated
waveforms:
• A lower case “r” (or “n” replaces the PSC number, in this case 0. However, when using the register or
• A lower case “x” replaces the PSCR part , in this case A or B. However, when using the register or bit
• “Two Outputs” to drive a half bridge (lighting, ...)
• “One Output” to drive single power transistor (DC/DC converter, PFC, ...)
• Current sensing regulation
• Zero crossing retriggering
• Demagnetization retriggering
• Fault input
PWM waveform generation function (2 complementary programmable outputs)
Dead time control
Standard mode up to 12 bit resolution
Enhanced resolution up to 16 bits
Frequency up to 64 Mhz
Conditional Waveform on External Events (Zero Crossing, Current Sensing ...)
ADC synchronization
Overload protection function
Abnormality protection function, emergency input to force all outputs to high impedance or in inactive state
(fuse configurable)
Fast emergency stop by hardware

and Output Configuration register and so on.
defines in a program, the precise form must be used, i.e., PFRC0A for accessing PSCR 0
