Description

DryIce Pin Glitch Filter Register

Fields

GFW

Glitch Filter Width
GFP

Glitch Filter Prescaler

0 (0): The glitch filter on tamper pin is clocked by the 512 Hz prescaler clock.

1 (1): The glitch filter on tamper pin is clocked by the 32.768 kHz clock.
GFE

Glitch Filter Enable

0 (0): The glitch filter on tamper pin is bypassed.

1 (1): The glitch filter on tamper pin is enabled.
TPSW

Tamper Pin Sample Width

0 (00): Tamper Pin Sampling is disabled.

1 (01): Tamper Pin Sample Width is 2 cycles for pull enable and 1 cycle for input buffer enable.

2 (10): Tamper Pin Sample Width is 4 cycles for pull enable and 2 cycles for input buffer enable.

3 (11): Tamper Pin Sample Width is 8 cycles for pull enable and 4 cycles for input buffer enable.
TPSF

Tamper Pin Sample Frequency

0 (00): Tamper Pin Sample Frequency is once every 8 cycles

1 (01): Tamper Pin Sample Frequency is once every 32 cycles

2 (10): Tamper Pin Sample Frequency is once every 128 cycles

3 (11): Tamper Pin Sample Frequency is once every 512 cycles
TPEX

Tamper Pin Expected

0 (00): Tamper pin expected value is logic zero.

1 (01): Tamper pin expected value is active tamper 0 output.

2 (10): Tamper pin expected value is active tamper 1 output.

3 (11): Tamper pin 0 expected value is active tamper 0 output XORed with active tamper 1 output.
TPE

Tamper Pull Enable

0 (0): Pull resistor is disabled on tamper pin.

1 (1): Pull resistor is enabled on tamper pin.
TPS

Tamper Pull Select

0 (0): Tamper pin pull direction will always assert the tamper pin.

1 (1): Tamper pin pull direction will always negate the tamper pin.
