SYMBOL
EA
Disables all interrupts. If EA=0, no interrupt will be acknowledged. If EA=1, each interrupt
source is individually enabled or disabled by setting or clearing its enable bit.
Enables or disables the Output Buffer Full (OBF) interrupt. If IOB=0, the interrupt is disabled,
If IOB=1, an interrupt will occur if EA is set and data has been read from the output buffer
register through Port 6 by the external host pulsing ODS low.
Enables or disables the Input Buffer Full (IBF) interrupt. If IIB=0, the interrupt is disabled. If
IIB=1, an interrupt will occur if EA is set and data has been written into the Port 6 Input Data
Buffer by the host strobing IDS low.
Enables or disables the Serial Port Interrupt. If ES=0, the Serial Port Interrupt. If ES=0, the
Serial Port interrupt is disabled.
Enables or disables the Timer 1 Overflow interrupt. If ET1=0, the Timer 1 interrupt is disabled.
Enables or disables External Interrupt 1. If EX1=0, External Interrupt 1 is disabled.
Enables or disables the Timer 0 Overflow interrupt. If ET0=0, the Timer 0 interrupt is disabled.
Enables or disables External Interrupt 0. If EX0=0, external Interrupt 0 is disabled.
