Texas Instruments Jacinto 7 DRA829 - Device Identification Settings; BUCK Settings

5.2 Device Identification Settings
These settings are used to distinguish which device is detected in a system. These settings cannot be changed
after device startup.

TPS65941213-Q1 TPS65941111-Q1
Value Description Value Description
DEV_REV DEVICE_ID 0x82 0x82
NVM_CODE_1 TI_NVM_ID 0x13 0x11
NVM_CODE_2 TI_NVM_REV 0x4 0x3
PHASE_CONFIG MP_CONFIG 0x3 3+1+1 0x0 4+1
5.3 BUCK Settings
These settings detail the voltages, configurations, and monitoring of the BUCK rails stored in the NVM. All these
settings can be changed though I
2
C after startup. Some settings, typically the enable bits, are also changed by
the PFSM, as described in Section 6.3.
After the Section 6.3.8 sequence has completed, the BUCKx_EN bit is set for BUCK1, BUCK4, and BUCK5 in
the TPS65941213. BUCKx_EN is set for the BUCK1 and BUCK5 in the TPS65941111. The BUCKx_VMON_EN
bit is set for BUCK1, BUCK3, BUCK4 and BUCK5 in the TPS65941213. The BUCKx_VMON_EN bit is set for
BUCK1 and BUCK5 in the TPS65941213. The BUCKx_RV_SEL bit is cleared for all BUCKs. The other bits
remain unchanged, but are still accessible via I
2
C.
