156 / 248 page ![]() TMP93CS40/TMP93CS41 2004-02-10 93CS40-154 3.10 Stepping Motor Control/Pattern Generation Port The TMP93CS40/TMP93CS41 contains two 4-bit hardware stepping motor control/pattern generation channels, PG0 and PG1, (hereinafter called PG) which actuate in synchronization with the (8-bit/16-bit) timers. PG (PG0 and PG1) shares the 8-bit input/output port with P6. The output on channel 0 (PG0) is updated in synchronization with the 8-bit timer 0, 8-bit timer 1, or 16-bit timer 4. The output on channel 1 (PG1) is updated in synchronization with the 8-bit timer 0, the 8-bit timer 1, or the 16-bit timer 5. The PG ports are controlled by the control register (PG01CR) and can select either stepping motor control mode or pattern generation mode. Each bit of P6 can be used for a PG port. PG0 and PG1 can be used independently. Since the two PG channels operate in the same manner, except for the following points, only the operation of PG0 will be explained below.
