Technical Data
SCI/MI 2 data high (S2DRH)
SCI/MI 2 data low (S2DRL)
SCI/MI 2 status 2 (S2SR2)
SCI/MI 2 status 1 (S2SR1)
The bits in S2SR1 indicate certain conditions in the SCI hardware and
are automatically cleared by special acknowledge sequences. For
details of the bits, see
In the S2SR2 only bit 0 is used, to indicate receiver active (see
— SCI status register
S2DRH/S2DRL 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.
See
SCI3 shares I/O with two of port H’s pins: receive pin RXD3/PH4 and
transmit pin TXD3/PD5. The SCI receive and transmit functions are
enabled by RE and TE respectively, in S3CR2.
