Operating Modes and On-Chip Memory
2.3.3.3 System Configuration Options Register
The 8-bit, special-purpose system configuration options register (OPTION) sets internal system
configuration options during initialization. The time protected control bits, IRQE, DLY, and CR[1:0], can
be written only once after a reset and then they become read-only. This minimizes the possibility of any
accidental changes to the system configuration.
ADPU — Analog-to-Digital Converter Power-Up Bit
CSEL — Clock Select Bit

Refer to
Selects alternate clock source for on-chip EEPROM charge pump. Refer to
CONFIG Programming and Erasure
CSEL also selects the clock source for the A/D converter, a function discussed in
Analog-to-Digital (A/D)
Chapter 3 Analog-to-Digital (A/D)
