PRODUCTION DATA
I2C based serial interface can be used for motor control by setting SPEED_MODE to 10b. In this mode, the speed command can be written directly into DIGITAL_SPEED_CTRL register. The SPEED pin can be used to control the sleep entry and exit - if SPEED pin input is set to a value lower than VEN_SL after DIGITAL_SPEED_CTRL register has been set to 0b for a time longer than SLEEP_ENTRY_TIME, MCF8316C-Q1 enters sleep state. When SPEED pin > VEX_SL, MCF8316C-Q1 exits sleep state and speed is controlled through DIGITAL_SPEED_CTRL register. If 0 ≤ DIGITAL_SPEED_CTRL register ≤ DIGITAL_SPEED_CTRLEN_SB and SPEED pin > VEX_SL, MCF8316C-Q1 is in standby state. The relationship between DUTY_CMD and DIGITAL_SPEED_CTRL register is shown in Figure 7-16. Refer Section 7.4.1.2 for more information on DIGITAL_SPEED_CTRLEN_SBEX_SB and DIGITAL_SPEED_CTRLEN_SBEN_SB.
