Configuration Register (CONFIG)
5.3 Functional Description
Technical Data
66
* URSTD and LVID bits are reset by POR or LVI reset only.
Address:
The configuration register is used in the initialization of various options.
The configuration register can be written once after each reset. Bit-5 and
bit-4 are cleared by a POR or LVI reset only. Bit-3 to bit-0 are cleared
during any 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 $001F. The configuration
register may be read at any time.
URSTD — USB Reset Disable Bit
LVID — Low Voltage Inhibit Disable Bit
SSREC — Short Stop Recovery Bit
Reset:
Read:
Write:
URSTD disables the USB reset signal generating an internal reset to
the CPU and internal registers. Instead, it will generate an interrupt
request to the CPU.
LVID disables the LVI circuit
SSREC enables the CPU to exit stop mode with a delay of
2048×OSCXCLK cycles instead of a 4096×OSCXCLK cycle delay.
1 = USB reset generates a USB interrupt request to CPU
0 = USB reset generates a chip reset
1 = Disable LVI circuit
0 = Enable LVI circuit
1 = Stop mode recovery after 2048×OSCXCLK cycles
0 = Stop mode recovery after 4096×OSCXCLK cycles
