SECTION 3
CONFIGURATION AND CONTROL
Registers of the QSM 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
4.3 QSPI Programmer's Model and Registers
and
5.2 SCI Programmer's Model and Registers
, respectively. Writes to unimplemented
bits have no meaning or effect, and reads from unimplemented bits always return a
logic zero value.
The modmap bit of the system integration module (SIM) module configuration register
(MCR) defines the most significant bit (ADDR23) of the address, shown in each regis-
ter figure as Y (Y = $7 or $F). This bit, concatenated with the rest of the address given,
forms the absolute address of each register.
Table 3-1
is a summary of the registers, bits, and reset states for the full QSM module.
As previously mentioned,
Table 3-2
is a quick reference guide to all the bits/fields of
the QSM module. Along with the function, the register and register location of each bit/
field are identified.
