PIC18F2480/2580/4480/4580 Data Sheet Errata

Clarifications/Corrections to the Data Sheet

In the PIC18F2480/2580/4480/4580 Device Data Sheet (DS39637C), the following clarifications and corrections should be noted. Any silicon issues related to this device will reported in a separate silicon errata. Please check the Microchip web site for any existing issues.

1. Module: Enhanced Capture/Compare PWM (ECCP1)

The following note has been added to the end of

Section 16.4.6 “Programmable Dead-Band Delay”.

Note: If the dead-band delay value is increased

after the dead-band time has elapsed, that new value takes effect immediately. This happens even if the PWM pulse is high and can appear to be a glitch. Dead-band values must be changed during the dead-band time or before ECCP is active.

2. Module: Master Synchronous Serial Port (MSSP) – Serial Peripheral Interface (SPI)

The following note has been added to the end of

Section 17.3.3 “Enabling SPI I/O”.

Note: When the module is enabled and in

Master mode (CKE, SSPSTAT<6> = 1), a small glitch of approximately half a T may be seen on the SCK pin. To resolve this, keep the SCK pin as an input while setting SPEN. Then, configure the SCK pin as an output (TRISC<3> = 0).
