The value of INTV0 used during an interrupt-acknowledge cycle is supplied by the QSM. During an in-
terrupt-acknowledge cycle, INTV[7:1] are driven on DATA[7:1] IMB lines. DATA0 is negated for an SCI
interrupt and asserted for a QSPI interrupt. Writes to INTV0 have no meaning or effect. Reads of INTV0
return a value of one.
5.4.2 Pin Control Registers
The QSM uses nine pins, eight of which form a parallel port (PORTQS) on the MCU. Although these
pins are used by the serial subsystems, any pin can alternately be assigned as general-purpose I/O on
a pin-by-pin basis.
Pins used for general-purpose I/O must not be assigned to the QSPI by register PQSPAR. To avoid
driving incorrect data, the first byte to be output must be written before DDRQS is configured. DDRQS
must then be written to determine the direction of data flow and to output the value contained in register
PORTQS. Subsequent data for output is written to PORTQS.
PORTQS latches I/O data. Writes drive pins defined as outputs. Reads return data present on the pins.
To avoid driving undefined data, first write a byte to PORTQS, then configure DDRQS.
Clearing a bit in PQSPAR assigns the corresponding pin to general-purpose I/O; setting a bit assigns
the pin to the QSPI. PQSPAR does not affect operation of the SCI. Table 52 displays PQSPAR pin as-
signments.
