OTP_READ_L

VL [1:0]

Selects the Margin Level for READ or VERIFY OTP

commands.

00 = Normal

01 = Reserved

10 = Margin 1

11 = Margin 2

Protected by security key.

OTP_BULK

Selects the number of memory pages for ICE / OTP

commands.

0 = Single Page

1 = All Pages

1:0

OTP_PAGE

[1:0]

commands (when OTP_BULK=0).

If OTP is selected (OTP_MEM = 1):

00 = Page 0

01 = Page 1

10 = Page 2

11 = Page 3

If ICE is selected (OTP_MEM = 0):

00 = Page 2

GPIO Level

GP12_LVL

GPIO12 level.

When GP12_FN = 0h and GP12_DIR = 0, write to this

bit to set a GPIO output.

Read from this bit to read GPIO input level.

When GP12_POL is 0, the register contains the

opposite logic level to the external pin.

GP11_LVL

GPIO11 level.

When GP11_FN = 0h and GP11_DIR = 0, write to this

bit to set a GPIO output.

Read from this bit to read GPIO input level.

When GP11_POL is 0, the register contains the

opposite logic level to the external pin.

GP10_LVL

GPIO10 level.

When GP10_FN = 0h and GP10_DIR = 0, write to this

bit to set a GPIO output.

Read from this bit to read GPIO input level.

When GP10_POL is 0, the register contains the

opposite logic level to the external pin.
