2.6 Register Descriptions
The remainder of this section lists and describes the GPTM registers, in numerical order by address
offset.

2.6.1 GPTM Configuration (GPTMCFG) Register, offset 0x000

The GPTM Configuration (GPTMCFG) register configures the global operation of the GPTM module. The
value written to this register determines whether the GPTM is in 32- or 16-bit mode.
Important: Bits in this register should only be changed when the TAEN and TBEN bits in the GPTMCTL
register are cleared.

2.6.2 GPTM Timer A Mode (GPTMTAMR) Register, offset 0x004

The GPTM Timer A Mode (GPTMTAMR) register configures the GPTM based on the configuration
selected in the GPTMCFG register. When in PWM mode, set the TAAMS bit , clear the TACMR bit, and
configure the TAMR field to 0x2.
