Table 3-109 SCC_MRAM_CTRL2 Register bit assignments
Bits
Name
Function
[31:16] TIME_TO_STOP
If autostop is enabled, number of
microseconds to wait in inactive mode before
going to STOP mode.
Reset value
0xFFFF
.
[15:8]
MRAM_CLK_DIV
eMRAM clock divider:
0x00
: No division (bypass).
0x01
: Divide by two (default).
0x10
: Divide by three.
0x11
: Divide by four.
Undefined values are not used.
Reset value
0x01
.
[7:0]
PRESCALE
Clock prescaler to generate the timebase for
the eMRAM clock. The value of PRESCALE
must always meet the following equality:
PRESCALE=eMRAM clock(MHz).
Preserving this equality generates a 1μS
timebase and ensures correct operation of the
eMRAM memory and clock.
If you adjust the eMRAM clock, you must
adjust PRESCALE to preserve the equality.
For example, if:
•
eMRAM clock =15MHz:
— PRESCALE=
0x0F
(15).
•
eMRAM clock =20MHz:
— PRESCALE=
0x14
(20).
•
eMRAM clock =30MHz:
— PRESCALE=
0x1E
(30).
Reset value
0x19
(25MHz).
