5.10.2.1 S3CR1 — SCI3 control register 1
5.10.2.2 S3CR2 — SCI3 control register 2
5.10.2.3 S3SR1 — SCI3 status register 1
MC68HC11P2 — Rev 1.0
SCI/MI 3 control 1 (S3CR1)
SCI/MI 3 control 2 (S3CR2)
SCI/MI 3 status 1 (S3SR1)
The S3CR1 register provides the control bits that determine word length
and select the method used for the wakeup feature. Bit 5 has an MI BUS
control function detailed below (for details of the other bits see
— SCI control register
MIE3 — Motorola Interface Bus Enable 3
The S3CR2 register provides the control bits that enable or disable
individual SCI functions. For details of the bits, see
control register
The bits in S3SR1 indicate certain conditions in the SCI hardware and
are automatically cleared by special acknowledge sequences. For
details of the bits, see
Freescale Semiconductor, Inc.
When MIE3 is set, the SCI3 registers, bits and pins assume the
functionality required for MI BUS.
