23.2.1 Register Description
The PIT programming model consists of these registers:
23.2.1.1 PIT Control and Status Register (PCSRn)
Freescale Semiconductor
• The PIT control and status register (PCSRn) configures the timer’s operation.
• The PIT modulus register (PMRn) determines the timer modulus reload value.
• The PIT count register (PCNTRn) provides visibility to the counter value.

S = CPU supervisor mode access only. S/U = CPU supervisor or user mode access. User mode accesses to
supervisor only addresses have no effect and result in a cycle termination transfer error.
Accesses to reserved address locations have no effect and result in a cycle termination transfer error.
