REGISTER 20-9: AD1PCFGH: ADC1 PORT CONFIGURATION REGISTER HIGH(1,2,3,4) R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 PCFG31 PCFG30 PCFG29 PCFG28 PCFG27 PCFG26 PCFG25 PCFG24 bit 15 bit 8 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 PCFG23 PCFG22 PCFG21 PCFG20 PCFG19 PCFG18 PCFG17 PCFG16 bit 7 bit 0 Legend: R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’ -n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown bit 15-0 PCFG<31:16>: ADC Port Configuration Control bits 1 = Port pin in Digital mode, port read input enabled, ADC input multiplexor connected to AVSS 0 = Port pin in Analog mode, port read input disabled, ADC samples pin voltage Note 1: On devices without 32 analog inputs, all PCFG bits are R/W by user. However, PCFG bits are ignored on ports without a corresponding input on device. 2: ADC2 only supports analog inputs AN0-AN15; therefore, no ADC2 high port Configuration register exists. 3: PCFGx = ANx, where x = 16 through 31. 4: PCFGx bits will have no effect if ADC module is disabled by setting ADxMD bit in the PMDx register. In this case all port pins multiplexed with ANx will be in Digital mode. REGISTER 20-10: ADxPCFGL: ADCx PORT CONFIGURATION REGISTER LOW(1,2,3,4) R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 PCFG15 PCFG14 PCFG13 PCFG12 PCFG11 PCFG10 PCFG9 PCFG8 bit 15 bit 8 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 PCFG7 PCFG6 PCFG5 PCFG4 PCFG3 PCFG2 PCFG1 PCFG0 bit 7 bit 0 Legend: R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’ -n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown bit 15-0 PCFG<15:0>: ADC Port Configuration Control bits 1 = Port pin in Digital mode, port read input enabled, ADC input multiplexor connected to AVSS 0 = Port pin in Analog mode, port read input disabled, ADC samples pin voltage Note 1: On devices without 16 analog inputs, all PCFG bits are R/W by user. However, PCFG bits are ignored on ports without a corresponding input on device. 2: On devices with 2 analog-to-digital modules, both AD1PCFGL and AD2PCFGL will affect the configuration of port pins multiplexed with AN0-AN15. 3: PCFGx = ANx, where x = 0 through 15. 4: PCFGx bits will have no effect if ADC module is disabled by setting ADxMD bit in the PMDx register. In this case all port pins multiplexed with ANx will be in Digital mode. |
