The PCLKCR1 and PCLKCR2 registers basically enable/disable clocks to the various peripheral modules in
the F2810 and F2812 devices. Table 32 lists the bit descriptions of the PCLKCR1 and PCLKCR2 registers.

NAME
TYPE
RESET
DESCRIPTION
0
EVAENCLK
R/W
0
If this bit is set, it enables the high-speed clock (HSPCLK) within the EV-A
peripheral. For low power operation, this bit is set to zero by the user or
by reset.
1
EVBENCLK
R/W
0
If this bit is set, it enables the high-speed clock (HSPCLK) within the EV-B
peripheral. For low power operation, this bit is set to zero by the user or
by reset.
2
reserved
R=0
0
reserved
3
ADCENCLK
R/W
0
If this bit is set, it enables the high-speed clock (HSPCLK) within the ADC
peripheral. For low power operation, this bit is set to zero by the user or
by reset.
7:4
reserved
R=0
0:0
8
SPIAENCLK
R/W
0
If this bit is set, it enables the low-speed clock (LSPCLK) within the SPI
peripheral. For low power operation, this bit is set to zero by the user or
by reset.
9
reserved
R=0
0
reserved
10
SCIAENCLK
R/W
0
If this bit is set, it enables the low-speed clock (LSPCLK) within the SCI-A
peripheral. For low power operation, this bit is set to zero by the user or
by reset.
11
SCIBENCLK
R/W
0
If this bit is set, it enables the low-speed clock (LSPCLK) within the SCI-B
peripheral. For low power operation, this bit is set to zero by the user or
by reset.
12
MAENCLK
R/W
0
If this bit is set, it enables the low-speed clock (LSPCLK) within the
McBSP peripheral. For low power operation, this bit is set to zero by the
user or by reset.
13
reserved
R=0
0
reserved
14
HECCAENCLK
R/W
0
If this bit is set, it enables the system clock within the CAN peripheral. For
low power operation, this bit is set to zero by the user or by reset.
15
reserved
R=0
0
reserved
If a peripheral block is not used, then the clock to that peripheral can be turned off to minimize power consumption.
