Clarifications and corrections to the PIC18F2480/2580/4480/4580 Device Data Sheet. Includes notes on the Enhanced Capture/Compare PWM module and the Master Synchronous Serial Port (MSSP) - Serial Peripheral Interface (SPI).
This errata supplement provides clarifications and corrections to the original PIC18F2480/2580/4480/4580 data sheet (DS39637C). It covers issues such as a small glitch on the ECCP1 PWM output, dead‑band delay behavior, and SPI I/O enabling details. The document also lists revision history, noting the removal of earlier flash‑memory errata and the addition of new MSSP‑SPI and ECCP1 notes.
Additional sections include a disclaimer on code‑protection features, trademark information, and worldwide sales and service contact details for Microchip offices across the Americas, Asia/Pacific and Europe.
If the dead‑band delay value is increased after the dead‑band time has elapsed, the new value takes effect immediately, even if the PWM pulse is high.
