5.10.2.5 S3DRH, S3DRL — SCI3 data high/low registers
Technical Data
SCI/MI 3 data high (S3DRH)
SCI/MI 3 data low (S3DRL)
SCI/MI 3 status 2 (S3SR2)
In S3SR2 only bit 0 is used, to indicate receiver active (see
SCI status register 2
S3DRH/S3DRL is a parallel register that performs two functions. It is the
receive data register when it is read, and the transmit data register when
it is written. Reads access the receive data buffer and writes access the
transmit data buffer. Data received or transmitted is double buffered.
