Chapter 3: LPC13xx System configuration
3.5.33 POR captured PIO status register 0
The PIOPORCAP0 register captures the state (HIGH or LOW) of the PIO pins of ports 0,1,
and 2 (pins PIO2_0 to PIO2_7) at power-on-reset. Each bit represents the reset state of
one GPIO pin. This register is a read-only status register.
3.5.34 POR captured PIO status register 1
The PIOPORCAP1 register captures the state (HIGH or LOW) of the PIO pins of port 2
(PIO2_8 to PIO2_11) and port 3 at power-on-reset. Each bit represents the reset state of
one PIO pin. This register is a read-only status register.
