PIC18F45J10 FAMILY
12. Module: EUSART
EXAMPLE 1:
DS80494B-page 6
;Initial conditions: SPEN = 0 (module disabled)
;To re-enable the module:
;Re-Initialize TXSTAx, BAUDCONx, SPBRGx, SPBRGHx registers (if needed)
;Re-Initialize RCSTAx register (if needed), but do not set SPEN = 1 yet
;Now enable the module, but add a 2-Tcy delay before executing any two-cycle
;instructions
bsf RCSTA1, SPEN;or RCSTA2 if EUSART2
nop ;1 Tcy delay
nop ;1 Tcy delay (two total)
;CPU may now execute 2 cycle instructions
In rare situations, when interrupts are enabled,
unexpected results may occur if:
• The EUSART is disabled (the SPEN bit,
• The EUSART is re-enabled (RCSTAx<7> = 1)
• A two-cycle instruction is executed immediately
RCSTAx<7> = 0)
after setting SPEN = 1
RE-ENABLING A EUSART MODULE
Work around
Add a 2 T
enables the EUSART module (sets SPEN = 1).
