CHAN_EN
Enables the read from the memory channel

0x0
Before enabling the memory read channel, the software
must:
- Disable the physical interface using the IF_EN bit
- Wait until disabling of the physical interface is effective
(depends on the FRAME bit)
Read from memory starts when this bit is set; therefore,
all CCP2_LCM_x registers must be configured correctly
before the bit is set.
This bit is cleared by hardware at the end of the frame.
0x0: Disabled
0x1: Enabled
