5.2.14
Interrupt enable register 0 (IE0) enables or disables the TXINT, RXINT, TXRDY, and RXRDY
interrupt requests. Interrupt requests are issued to the MPU when both the status register 0 (ST0)
bits and the corresponding bits of this register are set to 1. For details on interrupts, see section
5.7, Interrupts.
Bit 7 (TXINTE: TXINT Interrupt Enable): The function of this bit is described below.
Bit 6 (RXINTE: RXINT Interrupt Enable): The function of this bit is described below.
Asynchronous/Byte synchronous/Bit synchronous mode
TXINTE = 0: Disables an interrupt request set by the TXINT bit of ST0
TXINTE = 1: Enables an interrupt request set by the TXINT bit of ST0; a TXINT interrupt
request is issued to the MPU when the TXINT bit of ST0 is set to 1
Asynchronous/Byte synchronous/Bit synchronous mode.
RXINTE = 0: Disables an interrupt request set by the RXINT bit of ST0
RXINTE = 1: Enables an interrupt request set by the RXINT bit of ST0; a RXINT interrupt
request is issued to the MPU when the RXINT bit of ST0 is set to 1
