15.2.2.3.2 Controlling and Monitoring the Time-Base Submodule
Table 15-11 lists the registers used to control and monitor the time-base submodule.
Table 15-11. Time-Base Submodule Registers
Acronym Register Description Address Offset Shadowed
TBCTL Time-Base Control Register 0h No
TBSTS Time-Base Status Register 2h No
TBPHSHR HRPWM extension Phase Register
(1)
4h No
TBPHS Time-Base Phase Register 6h No
TBCNT Time-Base Counter Register 8h No
TBPRD Time-Base Period Register Ah Yes

This register is available only on ePWM instances that include the high-resolution extension (HRPWM). On ePWM modules that
do not include the HRPWM, this location is reserved. See Section 15.1.2 to determine which ePWM instances include this
feature.
Figure 15-10 shows the critical signals and registers of the time-base submodule. Table 15-12 provides
descriptions of the key signals associated with the time-base submodule.
