MCP37D31-80 AND MCP37D21-80

ADDRESS 0X82 – NUMERICALLY CONTROLLED OSCILLATOR TUNING (LOWER BYTE)

R/W-0

NCO_TUNE<7:0>

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 7-0

NCO_TUNE <7:0>: Lower byte of NCO_TUNE<31:0>(1)

0000-0000 = DC (0 Hz) when NCO_TUNE<31:0> = 0x00000000 (Default)

Note

See

Note 1 and Note 2 in Address 0x85 (Register 5-45).
