Table 9-4. MODE_CONF Register Field Descriptions (continued)

Bit Field Type Reset Description

19-18 XOSC_FREQ R/W 3h

Reserved for future use. Software should not rely on the value of a

reserved. Writing any other value than the reset/default value may

result in undefined behavior.

17 XOSC_CAP_MOD R/W 1h

Enable modification (delta) to XOSC cap-array. Value specified in

XOSC_CAPARRAY_DELTA. 0: Apply cap-array delta 1: Do not

apply cap-array delta (default)

16 HF_COMP R/W 1h

Reserved for future use. Software should not rely on the value of a

reserved. Writing any other value than the reset/default value may

result in undefined behavior.

15-8 XOSC_CAPARRAY_DEL R/W FFh

Signed 8-bit value, directly modifying trimmed XOSC cap-array step

value. Enabled by XOSC_CAP_MOD.

7-0 VDDR_CAP R/W FFh

Unsigned 8-bit integer, representing the minimum decoupling

capacitance (worst case) on VDDR, in units of 100nF. This should

take into account capacitor tolerance and voltage dependent

capacitance variation. This bit affects the recharge period calculation

when going into powerdown or standby. NOTE! Applying this field is

handled by the DriverLib functions

SysCtrlSetRechargeBeforePowerDown() and

SysCtrlAdjustRechargeAfterPowerDown() which should be called

before and after powerdown / standby respectively (handled

automatically if using TI RTOS!).
