Freescale Semiconductor, Inc.
General Description
Features
• 1M bit per second, CAN 2.0 A, B software compatible modules,
two on the MC68HC912DG128, each with:
– Two receive and three transmit buffers
– Flexible identifier filter programmable as 2 x 32 bit, 4 x 16 bit or
8 x 8 bit
– Four separate interrupt channels for Rx, Tx, error and wake-up
– Low-pass filter wake-up function
– Loop-back for self test operation
– Programmable link to a timer input capture channel, for time-
stamping and network synchronization.
• Enhanced capture timer (ECT)
– 16-bit main counter with 7-bit prescaler
– 8 programmable input capture or output compare channels; 4
of the 8 input captures with buffer
– Input capture filters and buffers, three successive captures on
four channels, or two captures on four channels with a
capture/compare selectable on the remaining four
– Four 8-bit or two 16-bit pulse accumulators
– 16-bit modulus down-counter with 4-bit prescaler
– Four user-selectable delay counters for signal filtering
• 4 PWM channels with programmable period and duty cycle
– 8-bit 4-channel or 16-bit 2-channel
– Separate control for each pulse width and duty cycle
– Center- or left-aligned outputs
– Programmable clock select logic with a wide range of
frequencies
