; Enable clock to ETM core.
;----------------------------------------------------------------------------

; Read the current value of the MSM_CLK_ENA0 register.

local &MSM_CLK_ENA0_ADDR
&MSM_CLK_ENA0_ADDR=0x84001400

local &MSM_CLK_ENA0_VAL
&MSM_CLK_ENA0_VAL=data.word(RD:&MSM_CLK_ENA0_ADDR)

; Now set bit 0 so that the ETM clock is enabled.

&MSM_CLK_ENA0_VAL=&MSM_CLK_ENA0_VAL|0x00000001
d.out &MSM_CLK_ENA0_ADDR %LONG &MSM_CLK_ENA0_VAL

; Set Trace32 ETM demux mode endianness convention.
;
; NOTE: This needs to be done *before* configuring the ETM core, or the
;       Trace32 software will not correctly decompress a trace. [07 May 2003]
