14 OVERVIEW OF PORT AND POWER-ON-RESET
CONFIGURATIONS
• The PCA335xC microcontrollers support one port and
Power-on-reset configuration which is compatible with
the OTP PCD3755E.
• The PCD335xA microcontrollers support two port and
Power-on-reset configurations which can be chosen:
one is compatible with the OTP PCD3755A, the other is
compatible with the OTP PCD3755E.

Notes
1. Port output drive: 1 = standard I/O; 2 = open-drain I/O, see “PCD33xxA Family” data sheet.
2. Port state after reset: S = Set (HIGH) and R = Reset (LOW).
3. The melody output drive type is push-pull.
