MAX14830
SpclCharInt—Special Character Interrupt Register
Bits 7, 6: No Function
Bit 5: MultiDropInt
The MultiDropInt interrupt is set when the MAX14830 receives an address character in 9-bit multidrop mode
(MODE2[6] = 1). This bit is cleared when SpclCharInt is read. The MultiDropInt bit can be routed to ISR[1] by enabling
SpclChrIntEn[5].
Bit 4: BREAKInt
The BreakInt interrupt is set when a line BREAK (RX_ low for longer than one character length) is detected by the
receiver. This bit is cleared after SpclCharInt is read. The BREAKInt interrupt can be routed to ISR[1] by enabling
SpclChrIntEn[4].
Bit 3: XOFF2Int
The XOFF2Int interrupt bit is set when an XOFF2 special character is received and special character detection is
enabled through MODE2[4]. This interrupt is cleared upon reading SpclCharInt. The XOFF2Int interrupt can be routed
to the ISR[1] interrupt bit, if enabled through SpclChrIntEn[3].
Bit 2: XOFF1Int
The XOFF1Int interrupt bit is set when an XOFF1 special character is received and special character detection is
enabled through MODE2[4]. This interrupt is cleared upon reading SpclCharInt. The XOFF1Int interrupt can be routed
to the ISR[1] interrupt bit, if enabled through SpclChrIntEn[2].
Bit 1: XON2Int
The XON2Int interrupt bit is set when an XON2 special character is received and special character detection is enabled
through MODE2[4]. This interrupt is cleared upon reading SpclCharInt. The XON2Int interrupt can be routed to the
ISR[1] interrupt bit, if enabled through SpclChrIntEn[1].
Bit 0: XON1Int
The XON1Int interrupt bit is set when an XON1 special character is received and special character detection is enabled
through MODE2[4]. This interrupt is cleared upon reading SpclCharInt. The XON1Int interrupt can be routed to the
ISR[1] interrupt bit, if enabled through SpclChrIntEn[0].
