MOTOR CONTROLLER (Cont’d)
Note: The CPB, HDM, SDM, OS2 bits in the
MCRB and the bits OE[5:0] are marked with *. It
means that these bits are taken into account at the
following commutation event (in normal mode) or
when a value is written in the MPHST register
when in direct access mode. For more details, re-
fer to the description of the DAC bit in the MCRA
register. The use of a Preload register allows all
the registers to be updated at the same time.
Warning: Access to Preload registers
Special care has to be taken with Preload regis-
ters, especially when using the ST7 BSET and
BRES instructions on MTC registers.
For instance, while writing to the MPHST register,
you will write the value in the preload register.
However, while reading at the same address, you
will get the current value in the register and not the
value of the preload register.
All preload registers are loaded in the real regis-
ters at the same time. In normal mode this is done
automatically when a C event occurs, however in
direct access mode (DAC bit=1) the preload regis-
ters are loaded as soon as a value is written in the
MPHST register.
