Configuration Register (CONFIG)
5.3 Functional Description
Technical Data
48
NOTE:
Address:
The configuration register is used in the initialization of various options.
The configuration register can be written once after each reset. All of the
configuration register bits are cleared during reset. Since the various
options affect the operation of the MCU it is recommended that this
register be written immediately after reset. The configuration register is
located at $001E and $001F, and may be read at anytime.
The CONFIG registers are one-time writable by the user after each
reset. Upon a reset, the CONFIG registers default to predetermined
settings as shown in
IRQPUD — IRQ1 Pin Pull-up control bit
LVIT1, LVIT0 — Low Voltage Inhibit trip voltage selection bits
