• Manufacturer Part Number: S912XEQ384J3MALR
• Description: S912XEQ Series 16 Bit 50 Mhz 384 KB Flash 24 KB Ram Microcontroller - LQFP-112
• Manufacturer: Freescale Semiconductor

Once concatenated mode is enabled (CONxx bits set in PWMCTL register), enabling/disabling the
corresponding 16-bit PWM channel is controlled by the low order PWMEx bit. In this case, the high order
bytes PWMEx bits have no effect and their corresponding PWM output is disabled.
In concatenated mode, writes to the 16-bit counter by using a 16-bit access or writes to either the low or
high order byte of the counter will reset the 16-bit counter. Reads of the 16-bit counter must be made by
16-bit access to maintain data coherency.
