21.4.16 IO_CFG2
The Input/Output Configuration 2 Register (IO_CFG2) selects output regulated supply and clock rates.
In the table above, note that reserved bits are grayed table cells and are not described in the bit description section. Reserved
bits should always be written with a value of ‘0’. For additional information, refer to the
GPIO chapter.

Description
These bits select output regulated supply
The Regulated I/O charge pump can operate with a maximum clock speed of 12 MHZ. The
REG_CLOCK[1:0] bits select clocking options for the regulator. Setting REG_CLOCK[1:0] to ‘10’
should be used with 24 MHz SYSCLK and ‘01’ should be used with 6/12 MHz SYSCLK.
