Register Descriptions

This section gives detailed descriptions of the user accessible registers and bits within the module. In cases

where the operation mode affects the functionality of the control register, the operation in each mode is

described.

NOTE

Bit functions can vary in different operating modes. The field descriptions

are labelled to indicate which modes use a particular field.

26.3.3.1

Mode Register 1(PSCMR1n)

PSCMR1 controls some of the module configurations. It can be read or written at any time. It is accessed

when the mode register pointer points to PSCMR1. The pointer is set to mode register 1 by reset or by a

set pointer command using the MISC[2:0] bits in the command register (PSCCR). The pointer points to

the next mode register, PSCMR2, after reading or writing PSCMR1.
