Functional overview
37/99
The IMC unit has the following features:
Three PWM outputs generated using a 10 or 16-bit PWM counter, one for each phase
U, V, W. Complimentary PWM outputs are also generated for each phase.
Choice of classic or zero-centered PWM generation modes
10 or 16-bit PWM counter clock is supplied through a programmable 8-bit prescaler of
the APB clock.
Programmable 6 or 10-bit dead-time generator to add delay to each of the three
complimentary PWM outputs
8-bit repetition counter
Automatic rotor speed measurement with 16-bit resolution. Schmitt trigger tachometer
input with programmable edge detection
Hardware asynchronous emergency stop input
A dedicated interrupt to CPU with eight flags
Enhanced Motor stop output polarity configuration
Double update option when PWM counter reaches the max and min values in Zero-
centered mode
Locking feature to prevent some control register bits from being advertently modified
Trigger output to start an ADC conversion

External memory interface (EMI)
STR91xFA devices in 128-pin and 144-ball packages offer an external memory bus for
connecting external parallel peripherals and memories. The EMI bus resides on ports 7, 8,
and 9 and operates with either an 8 or 16-bit data path. The configuration of 8 or 16 bit
mode is specified by CPU firmware writing to configuration registers at run-time. If the
application does not use the EMI bus, then these port pins may be used for general purpose
I/O as shown in
Table 9
.
The EMI has the following features:
Supports static asynchronous memory access cycles, including page mode for non-
mux operation. The bus control signals include:
–
EMI_RDn - read signal, x8 or x16 mode
–
EMI_BWR_WRLn - write signal in x8 mode and write low byte signal in x16 mode
–
EMI_WRHn - write high byte signal in x16 mode
–
EMI_ALE - address latch signal for x8 or x16 mux bus mode with programmable
polarity
Four configurable memory regions, each with a chip select output (EMI_CS0n ...
EMI_CS3n)
Programmable wait states per memory region for both write and read operations
16-bit multiplexed data mode
(
Figure 4
): 16 bits of data and 16 bits of low-order
address are multiplexed together on ports 8 and 9, while port 7 contains eight more
high-order address signals. The output signal on pin EMI_ALE is used to demultiplex
the signals on ports 8 and 9, and the polarity of EMI_ALE is programmable. The output
signals on pins EMI_BWR_WRLn and EMI_WRHn are the write strobes for the low and
