5.3 Pin Function
Table 36
is a summary of the functions of the QSM pins when they are not configured for general-pur-
pose I/O. The QSM data direction register (DDRQS) designates each pin except RXD as an input or
output.
5.4 QSM Registers
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 SIML configuration register (SIMLCR) 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 SIML section of
this technical summary for more information about how the state of MM affects the system.
5.4.1 Global Registers
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.
