3.7 Stepping Motor Control/Pattern Generation Port (P4,
P5)
The TMP90C051F has a built-in, timer-coupled, 4-bit, 2-channel
(M0 and M1) hardware stepping motor control/pattern generation
port (hereafter called SMC). SMC (M0 and M1) is also used as
4-bit input/output ports P4 and P5.
Channel 0 (M0) is coupled to 8-bit timer 0 or timer 1, and
channel 1 (M1) is coupled to 8-bit timer 2 or timer 3, to alter
output.
SMC is controlled by two control registers (P45CR and
P45FR) and is used to select the stepping motor control mode
and pattern generation mode.
3.7.1 Control Registers
(1)
Ports 4 and 5 Input/Output Specification Register
(P45CR)
This register is specifies 4-bit input/output port 5 input
and output in 1-bit units. All P45CR bits are cleared to
“0” by resets, which sets ports 4 and 5 for input. To
use ports 4 and 5 as SMC, set all P45CR bits to “1”
for output.
The P45CR register can only be written, and cannot
be read.
(2)
Ports 4 and 5 Function Control Register (P45FR)
This register is used to set ports 4 and 5 for use as
SMC. To use ports 4 and 5 as SMC, set P45FR
<M0S, M1S> and P45FR4 (M1S) to “1”.
SMC is set to the 8-bit write mode or 4-bit write mode
with P45FR <PAT0> and P45FR <PAT1>. When writ-
ing to SMC in the 4-bit write mode, it is only possible
to write to the 4-bit shift alternate register and SMC func-
tions as the pattern generation port.
To use SMC as the stepping motor control port, the
method of excitation is selected with P45FR <M0M>
and P45FR <M1M>; P45FR <CCW0> and P45FR <
CCW1> control the direction of rotation.
(3)
Port 4
This is a 4-bit input/output port assigned to address
FFB9.
The 4 lower bits correspond to port 4 and the 4 upper
bits are a shift alternate register P4 <SA43 ~ 40>
used to drive the stepping motor in the pattern gener-
ation mode of with 1-2 excitations.
(4)
Port 5
This is a 4-bit input/output port assigned to address
FFBA.
The 4 lower bits correspond to port 5, and the 4 upper
bits are a shift alternate register P5 <SA53 ~ 50> used
to drive the stepping motor in the pattern generation mode
of with 1-2 excitations.
