3.4.5 Peripheral power control
3.4.6 Power control register description
3.4.7 Power Mode Control register (PCON - 0xE01F C0C0)
A Power Control for Peripherals feature allows individual peripherals to be turned off if
they are not needed in the application, resulting in additional power savings. This is
detailed in the description of the PCONP register.
The Power Control function uses registers shown in
descriptions follow.
Table 59.
[1]
Reduced power modes are controlled via the PCON register, as described in
Table 60.

Power Control registers
Power Mode Control register (PCON - address 0xE01F C0C0) bit description
Description
Power Control Register. This register
contains control bits that enable the two
reduced power operating modes of the
LPC2400. See
interrupts will wake the LPC2400 from
power-down mode. See
Power Control for Peripherals Register. This
register contains control bits that enable and
disable individual peripheral functions,
allowing elimination of power consumption by
peripherals that are not needed.
Description
Power mode control bit 1. See
Brown-Out Power-down Mode. When BODPDM is 1, the Brown-Out
Detect circuitry will turn off when chip Power-down mode is entered,
resulting in a further reduction in power usage. However, the possibility
of using Brown-Out Detect as a wakeup source from Power-down mode
will be lost.
When 0, the Brown-Out Detect function remains active during
Power-down mode.
See
Brown-Out Global Disable. When BOGD is 1, the Brown-Out Detect
circuitry is fully disabled at all times, and does not consume power.
When 0, the Brown-Out Detect circuitry is enabled.
