Section 18.0 “10-bit/12-bit Analog-
to-Digital Converter (ADC)”
Updated ADC Conversion Clock Select bits in the AD1CON3 register from
ADCS<5:0> to ADCS<7:0>. Any references to these bits have also been
updated throughout this data sheet (Register 18-3).
Updated Note 3 reference in Figure 18-1.
Replaced Figure 18-1 (ADC1 Module Block Diagram for
dsPIC33FJ12GP201) and added Figure 18-2 (ADC1 Block Diagram for
dsPIC33FJ12GP202).
Removed Equation 17-1: ADC Conversion Clock Period and Figure 17-2:
ADC Transfer Function (10-Bit Example).
Added Note 2 to Figure 18-3: ADC Conversion Clock Period Block Diagram.
Updated ADC1 Input Channel 1, 2, 3 Select Register (see Register 18-4) as
follows:
• Changed bit 10-9 (CH123NB - dsPIC33FJ12GP201 devices only)
description for bit value of 10 (if AD12B = 0).
• Updated bit 8 (CH123SB) to reflect device-specific information.
• Updated bit 0 (CH123SA) to reflect device-specific information.
• Changed bit 2-1 (CH123NA - dsPIC33FJ12GP201 devices only)
description for bit value of 10 (if AD12B = 0).
Updated ADC1 Input Channel 0 Select Register (see Register 18-5) as
follows:
• Changed bit value descriptions for bits 12-8
• Changed bit value descriptions for bits 4-0 (dsPIC33FJ12GP201
devices)
Modified Notes 1 and 2 in the ADC1 Input Scan Select Register Low (see
Register 18-6)
Modified Notes 1 and 2 in the ADC1 Port Configuration Register Low (see
Register 18-7)
Section 19.0 “Special Features” Added FICD register information for address 0xF8000E in the Device
Configuration Register Map (see Table 19-1).
Added FICD register content (BKBUG, COE, JTAGEN, and ICS<1:0> to the
dsPIC33FJ12GP201/202 Configuration Bits Description (see Table 19-2).
Added a note regarding the placement of low-ESR capacitors, after the
second paragraph of Section 19.2 “On-Chip Voltage Regulator” and to
Figure 19-1.
Removed the words “if enabled” from the second sentence in the fifth
paragraph of Section 19.3 “BOR: Brown-Out Reset”
