• The parameter RAM values that pertain to the SMCx transmitter can only be written
• The parameter RAM values that pertain to the SMCx receiver can only be written when:
when the TEN bit in the SMCMR is zero or after the STOP TRANSMIT command is
issued, but before the RESTART TRANSMIT command is issued.

ADDRESS
The REN bit in the SMCMR is zero.
The receiver is previously enabled after the ENTER HUNT MODE command is
issued.
The CLOSE RX BD command is issued before the REN bit is set.
You are only responsible for initializing the items in bold.
SMCx Base = (IMMR & 0xFFFF0000) + 0x3E80 (SMC1) and 0x3F80 (SMC2).
