5.10.1.1 S2BDH, S2BDL — SCI2/3 baud rate control registers
5.10.1.2 S2CR1 — SCI2 control register 1
5.10.1.3 S2CR2 — SCI2 control register 2
MC68HC11P2 — Rev 1.0
SCI/MI 2/3 baud high (S2BDH)
SCI/MI 2/3 baud low (S2BDL)
SCI/MI 2 control 2 (S2CR2)
SCI/MI 2 control 1 (S2CR1)
The contents of this register determine the baud rate for both SCI2 and
SCI3. For details of the bits and the corresponding baud rates see
SCBDH, SCBDL — SCI baud rate control
controls the MI BUS clock rate (see
(MI
The S2CR1 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
MIE2 — Motorola interface bus enable 2
The S2CR2 register provides the control bits that enable or disable
individual SCI functions. For details of the bits, see
Freescale Semiconductor, Inc.
When MIE2 is set, the SCI2 registers, bits and pins assume the
functionality required for MI BUS.
