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.
