4.5.23 POR captured PIO status register 1
4.5.24 IOCONFIG clock divider registers 0 to 6
4.5.25 BOD control register
Table 29.
The PIOPORCAP1 register captures the state (HIGH or LOW) of the PIO pins of port 2
(PIO2_8 to PIO2_11) at power-on-reset. Each bit represents the reset state of one PIO
pin. This register is a read-only status register.
Table 30.
These registers individually configure the seven peripheral input clocks to the IOCONFIG
programmable glitch filter. The clocks can be shut down by setting the DIV bits to 0x0.
Table 31.
The BOD control register selects three separate threshold values for sending a BOD
interrupt to the NVIC and for forced reset. Reset and interrupt threshold values listed in
Table 32
The reset value of the BODCTRL register is not affected by a system reset. Instead, the
BODCTRL register retains its last programmed value.
The BOD control circuit is only reset by POR.
