Abstract
The present invention discloses a parity detection device and method in a CDMA mobile communications system, which detects parity error in data output from a cell site modem (Q51601-2S1), and controls the data output when the parity error occurs, to improve the reliability in data communication. The invention converts serial data to be transmitted through a CSM into parallel data, checks if there is a parity error in the parallel data, and generates an interrupt when a parity error is detected. When the interrupt is generated, an output controller restrains the transmission of the serial data to be transmitted, which is outputted from the CSM, thereby preventing data having error from being transmitted.
