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
Work around

Disable the EUSART (RCSTA<7> = 0).
Re-enable the EUSART (RCSTA<7> = 1).
Re-enable receive interrupts (PIE1<5> = 1).
