Errata Document MB91520 Series D/A converter When the output pin of the D/A converter is used as the I/O port, write "0" to corresponding bits in the port function register "PFRxx (xx = 00 to 19)". D/A converter is now outputting Write the key codes to corresponding bits in KEYCDR Write 0 to corresponding bits in PFRxx General-purpose port function enabled Corrective action by Cypress Cypress will revise the Waveform generator and D/A converter of the affected devices. The part numbers will be changed from MB91F52xxxB to MB91F52xxxC. Details of the revisions are as follows: Waveform generator: Revision will be made so that the output pin of the waveform generator can function as an I/O port after the output is disabled by the use of the "DTTI" function. D/A converter: Revision will be made so that the output pin can perform the following functions: -The output pin functions as an I/O port after the output is disabled by the setting of the D/A control register "DACR". -The output pin functions as an I/O port when the D/A converter is stopped due to the switching to stop mode or watch mode.
