21.3 Current Source Control Register

(1)

R/W-0 U-0 U-0 U-0 U-0 R/W-0 R/W-0 R/W-0

ISRCEN — — — — OUTSEL<2:0>

bit 15 bit 8

U-0 U-0 R-0 R-0 R-0 R-0 R-0 R-0

— — ISRCCAL<5:0>

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 ISRCEN: Current Source Enable bit

1 = Current source is enabled

0 = Current source is disabled

bit 14-11 Unimplemented: Read as ‘0’

bit 10-8 OUTSEL<2:0>: Output Current Select bits

111 = Reserved

110 = Reserved

101 = Reserved

100 = Select input pin, ISRC4 (AN4)

011 = Select input pin, ISRC3 (AN5)

010 = Select input pin, ISRC2 (AN6)

001 = Select input pin, ISRC1 (AN7)

000 = No output is selected

bit 7-6 Unimplemented: Read as ‘0’

bit 5-0 ISRCCAL<5:0>: Current Source Calibration bits

The calibration value must be copied from Flash address, 0x800840, into these bits. Refer to the

Constant Current Source Calibration Register (Register 22-1) in Section 22.0 “Special Features”

for more information.

Note 1: This register is available in the dsPIC33FJ09GS302 device only.
