Bidirectional pins: PIO0–PIO11, RFS0, RFS1, TFS0, TFS1, SCLK0, SCLK1.
2
Input only pins:
PWMTRIP
, PWMPOL,
RESET
, EIA, EIB, EIZP, DR1A, DR1B, DR0, CLKIN.
3
Output pins: PWMSYNC, CL, CH, BL, BH, AL, AH, MUX0–MUX2, AUX0, AUX1, CLKOUT, DT0, DT1.
4
Input only pins:
RESET
, EIA, EIB, EIZP, DR1A, DR1B, DR0, CLKIN.
5
Three-stateable pins: DT0, DT1, RFS0, RFS1, TFS0, TFS1, SCLK0, SCLK1.
6
Current reflects device operating with no output loads.
7
Dynamic condition refers to continuous operation of the DSP core, ADC banks and PWM generation in single update mode with PWMTM = 0x0480, ADCDIVA =
ADCDIVB = 0x180. The encoder inputs are quiescent.
8
Disabled refers to powering down both ADC banks and the internal reference generation circuit by setting Bits 10, 11 and 12 of the ADCCTRL register. Current is
total current from AV
DD
supply.
