MC68332TS/D
FQM counts the number of input pulses to a TPU channel during a user-defined window period. The
function has single shot and continuous modes. No pulses are lost between sample windows in contin-
uous mode. The user selects whether to detect pulses on the rising or falling edge. This function is in-
tended for high speed measurement; measurement of slow pulses with noise rejection can be made
with PTA.
This function decodes the sensor signals from a brushless motor, along with a direction input from the
CPU, into a state number. The function supports two- or three-sensor decoding. The decoded state
number is written into a COMM channel, which outputs the required commutation drive signals. In ad-
dition to brushless motor applications, the function can have more general applications, such as decod-
ing “option” switches.
The TPU control register address map occupies 512 bytes. The “Access” column in the TPU address
map below indicates which registers are accessible only at the supervisor privilege level and which can
be assigned to either the supervisor or user privilege level, according to the value of the SUPV bit in the
TPUMCR.
Y = M111, where M represents the logic state of the module mapping (MM) bit in the SIMCR.
