MC68HC916X1TS/D
In master mode, the QSPI executes a queue of commands defined by control bits in each command
RAM queue entry. Chip-select pins are activated, data is transmitted from transmit RAM and re-
ceived into receive RAM.
In slave mode, operation proceeds in response to SS pin activation by an external bus master. Op-
eration is similar to master mode, but no peripheral chip selects are generated, and the number of
bits transferred is controlled in a different manner. When the QSPI is selected, it automatically ex-
ecutes the next queue transfer to exchange data with the external device correctly.
Although the QSPI inherently supports multi-master operation, no special arbitration mechanism is
provided. A mode fault flag (MODF) indicates a request for SPI master arbitration. System software
must provide arbitration. Note that unlike previous SPI systems, MSTR is not cleared by a mode
fault being set, nor are the QSPI pin output drivers disabled. The QSPI and associated output driv-
ers must be disabled by clearing SPE in SPCR1.
7.5 SCI Submodule
The SCI submodule is used to communicate with external devices through an asynchronous serial
bus. The SCI is fully compatible with the SCI systems found on other Motorola MCUs, such as the
M68HC11 and M68HC05 Families.
7.5.1 SCI Pins
There are two unidirectional pins associated with the SCI. The SCI controls the transmit data (TXD)
pin when enabled, whereas the receive data (RXD) pin remains a dedicated input pin to the SCI.
TXD is available as a general-purpose I/O pin when the SCI transmitter is disabled. When used for
I/O, TXD can be configured either as input or output, as determined by QSM register DDRQS.
Table 60 shows SCI pins and their functions.
7.5.2 SCI Registers
The SCI programming model includes QSM global and pin control registers, and four SCI registers.
There are two SCI control registers, one status register, and one data register. All registers can be
read or written at any time by the CPU.
Changing the value of SCI control bits during a transfer operation may disrupt operation. Before
changing register values, allow the transmitter to complete the current transfer, then disable the re-
ceiver and transmitter. Status flags in the SCSR may be cleared at any time.
