PWR_PowerDown
Function
Arguments
mcbsp2
PDCTL Value
Use this macro to make a value suitable for the power-down control
register.
The power-on default value is PWR_PDCTL_DEFAULT.
Use of the PWR_MK_PDCTL macro makes it easier to construct regis-
ter values based on field values. You have a choice of using integer
constants, integer variables, or the symbolic constants for arguments.
All field values are right justified.
Refer to the TMS320C6000 Peripherals Reference Guide (literature
number SPRU190) for descriptions of the arguments.
