//! The main purpose of this function is to manage the SCARD buffer system. Any
//! buffers configured by \e am_hal_scard_buffer_configure will be managed by
//! this service routine. Data queued for transmit will be added to the SCARD TX
//! FIFO as space allows, and data stored in the SCARD RX FIFO will be copied

//! becomes idle via the optional \e pui32ScardTxIdle argument. This function
//! will set this variable any time it completes its operation and the SCARD TX
//! channel is no longer in use (including both the FIFO and any configured
//! buffer).
//!
//! For RTOS-enabled cases, this function does not necessarily need to be
//! called inside the actual ISR for the SCARD, but it should be called promptly
//! in response to the receipt of a SCARD TX, RX, or RX timeout interrupt. If
//! the service routine is not called quickly enough, the caller risks an RX
//! FIFO overflow (data can be lost here), or a TX FIFO underflow (usually not
//! harmful).
