MOTOROLA
The G mask set (or motion control mask set) includes the following functions:
The TPU consists of two 16-bit time bases, sixteen independent timer channels, a task
scheduler, a microengine, and a host interface. In addition, a dual-ported parameter
RAM is used to pass parameters between the module and the CPU32.
Two 16-bit counters provide reference time bases for all output compare and input
capture events. Prescalers for both time bases are controlled by the CPU32 via bit
fields in the TPU module configuration register (TPUMCR). Timer count registers
TCR1 and TCR2 provide access to the current counter values. TCR1 and TCR2 can
be read by TPU microcode, but are not directly available to the CPU32. The TCR1
clock is derived from the system clock. The TCR2 clock can be derived from the sys-
tem clock or from an external clock input via the T2CLK pin.
The TPU has 16 independent channels, each connected to an MCU pin. The channels
have identical hardware. Each channel consists of an event register and pin control
logic. The event register contains a 16-bit capture register, a 16-bit compare/match
register, and a 16-bit greater-than-or-equal-to comparator. The direction of each pin,
either output or input, is determined by the TPU microengine. Each channel can either
use the same time base for match and capture, or can use one time base for match
and the other for capture.
