20.8.3 TIM Counter Modulo Registers
68HC908AZ32A — Rev 0.0
MOTOROLA
NOTE:
Address: $004E:$004F
Address: $004E:$004F
The read/write PIT modulo registers contain the modulo value for the PIT
counter. When the PIT counter reaches the modulo value the overflow
flag (POF) becomes set and the PIT counter resumes counting from
$0000 at the next clock. Writing to the high byte (PMODH) inhibits the
POF bit and overflow interrupts until the low byte (PMODL) is written.
Reset sets the PIT counter modulo registers.
Reset the PIT counter before writing to the PIT counter modulo registers.
