95 / 107 page  Multiple Channel Capacitive Touch Sensor and LED Driver Datasheet SMSC CAP1214 95 Revision 1.0 (08-30-10) DATASHEET APPLICATION NOTE: When operating in Direct behavior mode, changes to the Duty Cycle settings will be applied immediately. When operating in Breathe, Pulse 1, or Pulse 2 modes, the LED must be unactuated and then re-actuated before changes to behavior are processed. Bits 7 - 4 - LED_X_MAX_DUTY[3:0] - Determines the maximum PWM duty cycle for the LED drivers as shown in Table 6.84 Bits 3 - 0 - LED_X_MIN_DUTY[3:0] - Determines the minimum PWM duty cycle for the LED drivers as shown in Table 6.84. 6.58 LED Direct Ramp Rates Register The LED Direct Ramp Rates Register control the rising and falling edge time of an LED that is configured to operate in Direct behavior mode. The rising edge time corresponds to the amount of time the LED takes to transition from its minimum duty cycle to its maximum duty cycle. Conversely, the Table 6.84 LED Duty Cycle Decode X_MAX/MIN_DUTY [3:0] MAXIMUM DUTY CYCLE MINIMUM DUTY CYCLE 32 1 0 0 0 0 0 7% 0% 0 0 0 1 9% 7% 00 1 0 11% 9% 00 1 1 14% 11% 0 1 0 0 17% 14% 0 1 0 1 20% 17% 0 1 1 0 23% 20% 0 1 1 1 26% 23% 1 0 0 0 30% 26% 1 0 0 1 35% 30% 1 0 1 0 40% 35% 1 0 1 1 46% 40% 1 1 0 0 53% 46% 1 1 0 1 63% 53% 1 1 1 0 77% 63% 1 1 1 1 100% 77% Table 6.85 LED Direct Ramp Rates Register ADDR R/W REGISTER B7 B6 B5 B4 B3 B2 B1 B0 DEFAULT 94h R/W LED Direct Ramp Rates - - RISE_RATE[2:0] FALL_RATE[2:0] 00h |
