23.3.3 Timeout Specifications
The 16-bit PIT counter and prescaler supports different timeout periods. The prescaler divides the
internal bus clock period as selected by the PCSRn[PRE] bits. The PMRn[PM] bits select the
timeout period.
23.3.4 Interrupt Operation
Table 23-4
The PIF flag is set when the PIT counter reaches 0x0000. The PIE bit enables the PIF flag to
generate interrupt requests. Clear PIF by writing a 1 to it or by writing to the PMR.
Freescale Semiconductor
