MSSP Driver Melody Module
Overview
The Host Synchronous Serial Port (MSSP) module is a serial interface useful for communicating with other peripheral or microcontroller devices. These peripheral devices may be serial EEPROMs, shift registers, display drivers, A/D converters, etc.
The MSSP module can operate in one of two modes:
- Serial Peripheral Interface (SPI)
- Inter-Integrated Circuit (I2C)
Features
The SPI and I2C interface supports the following operating modes:
- Host mode
- Client mode
The driver operation can be configured as:
- Polling
- Interrupt

[7.0.3] - 2024-12-18
Bug Fixes
- M8PD-12295 :- Updated I2Cx_IsBusy API in MSSP host driver to remove S bit check in SSP1STAT register
- M8PD-7589 :- Modified the client driver error handler to clear the SSPOV bit if it is set by hardware, preventing the bus from locking up
- M8PD-5173 :- Corrected the wrongly set read-only SSPxSTAT bit during I2C client operations, with the default set to zero
