The following table is a summary of the functions of the QSM pins when they are not configured for gen-
eral-purpose I/O. The QSM data direction register (DDRQS) designates each pin except RXD as an in-
put or output.
QSM registers are divided into four categories: QSM global registers, QSM pin control registers, QSPI
submodule registers, and SCI submodule registers. The QSPI and SCI registers are defined in separate
sections below. Writes to unimplemented register bits have no meaning or effect, and reads from unim-
plemented bits always return a logic zero value.
The module mapping bit of the SIM configuration register (SIMCR) defines the most significant bit
(ADDR23) of the address, shown in each register figure as Y (Y = $7 or $F). This bit, concatenated with
the rest of the address given, forms the absolute address of each register. Refer to the SIM section of
this technical summary for more information about how the state of MM affects the system.
The QSM global registers contain system parameters used by both the QSPI and the SCI submodules.
These registers contain the bits and fields used to configure the QSM.
The QSMCR contains parameters for the QSM/CPU/intermodule bus (IMB) interface.
STOP places the QSM in a low-power state by disabling the system clock in most parts of the module.
The QSMCR is the only register guaranteed to be readable while STOP is asserted. The QSPI RAM is
not readable. However, writes to RAM or any register are guaranteed to be valid while STOP is assert-
ed. STOP can be negated by the CPU and by reset.
0 = Normal QSM clock operation
1 = QSM clock operation stopped
