Macro Definition Documentation

TIS_PC_ACC_ACTIVE

#define TIS_PC_ACC_ACTIVE   BIT5

Indicate that this locality is active.

Definition at line 114 of file TpmTis.h.

TIS_PC_ACC_ESTABLISH

#define TIS_PC_ACC_ESTABLISH   BIT0

A value of 1 indicates that a T/OS has not been established on the platform

Definition at line 137 of file TpmTis.h.

TIS_PC_ACC_PENDIND

#define TIS_PC_ACC_PENDIND   BIT2

When this bit is 1, another locality is requesting usage of the TPM.

Definition at line 129 of file TpmTis.h.

TIS_PC_ACC_RQUUSE

#define TIS_PC_ACC_RQUUSE   BIT1

Set to 1 to indicate that this locality is requesting to use TPM.

Definition at line 133 of file TpmTis.h.

TIS_PC_ACC_SEIZE

#define TIS_PC_ACC_SEIZE   BIT3

Set to 1 to indicate that TPM MUST reset the TIS_PC_ACC_ACTIVE bit and remove ownership for localities less than the locality that is writing this bit.

Definition at line 125 of file TpmTis.h.

TIS_PC_ACC_SEIZED

#define TIS_PC_ACC_SEIZED   BIT4

Set to 1 to indicate that this locality had the TPM taken away while this locality had the TIS_PC_ACC_ACTIVE bit set.

Definition at line 119 of file TpmTis.h.

TIS_PC_STS_CANCEL

#define TIS_PC_STS_CANCEL   BIT24

Write a 1 to this bit to notify TPM to cancel currently executing command

Definition at line 142 of file TpmTis.h.

TIS_PC_STS_DATA

#define TIS_PC_STS_DATA   BIT4

This bit indicates that the TPM has data available as a response.

Definition at line 159 of file TpmTis.h.

TIS_PC_STS_EXPECT

#define TIS_PC_STS_EXPECT   BIT3

The TPM sets this bit to a value of 1 when it expects another byte of data for a command.

Definition at line 163 of file TpmTis.h.

TIS_PC_STS_GO

#define TIS_PC_STS_GO   BIT5

Write a 1 to this bit to cause the TPM to execute that command.

Definition at line 155 of file TpmTis.h.

TIS_PC_STS_READY

#define TIS_PC_STS_READY   BIT6

When this bit is 1, TPM is in the Ready state, indicating it is ready to receive a new command.

Definition at line 151 of file TpmTis.h.

TIS_PC_STS_RETRY

#define TIS_PC_STS_RETRY   BIT1

Writes a 1 to this bit to force the TPM to re-send the response.

Definition at line 171 of file TpmTis.h.

TIS_PC_STS_SELFTEST_DONE

#define TIS_PC_STS_SELFTEST_DONE   BIT2

Indicates that the TPM has completed all self-test actions following a TPM_ContinueSelfTest command.

Definition at line 167 of file TpmTis.h.

TIS_PC_STS_VALID

#define TIS_PC_STS_VALID   BIT7

This field indicates that STS_DATA and STS_EXPECT are valid

Definition at line 146 of file TpmTis.h.

TIS_PC_VALID

#define TIS_PC_VALID   BIT7

This bit is a 1 to indicate that the other bits in this register are valid.

Definition at line 110 of file TpmTis.h.

TIS_TIMEOUT_A

#define TIS_TIMEOUT_A   (750 * 1000)

Definition at line 176 of file TpmTis.h.

TIS_TIMEOUT_B

#define TIS_TIMEOUT_B   (2000 * 1000)

Definition at line 177 of file TpmTis.h.

TIS_TIMEOUT_C

#define TIS_TIMEOUT_C   (750 * 1000)

Definition at line 178 of file TpmTis.h.

TIS_TIMEOUT_D

#define TIS_TIMEOUT_D   (750 * 1000)

Definition at line 179 of file TpmTis.h.
