In rare situations when interrupts are enabled,
unexpected results may occur if:
• The EUSART is disabled (the SPEN bit,
• The EUSART is re-enabled (RCSTA <7> = 1)
• A two-cycle instruction is executed

Disable the EUSART (RCSTA <7>, = 0).
Re-enable the EUSART (RCSTA <7> = 1).
Re-enable Receive Interrupts (PIE1<5> = 1).
