NOTE
Unless otherwise noted the abbreviation NVM (Non-Volatile Memory) is
used for both program Flash and data Flash.
The time base for all program and data Flash operations, fNVMOP, is derived from the IPS bus clock, fIPS,
using the CFMCLKD register to control the divider ratio. Throughout this section, tIPS refers to 1 ÷ fIPS,
and tNVMOP refers to 1 ÷ fNVMOP. An fNVMOP frequency range limit is imposed for performing program
or erase operations. The CFM does not monitor the frequency and will not prevent program or erase
operation at frequencies above or below the following limits:
Eqn. 19
fNVMOP = 200 KHz gives the fastest program and erase performance. Setting CFMCLKD to a value such
that fNVMOP < 150 KHz should be avoided, as this can damage the Flash memory due to overstress. Setting
CFMCLKD to a value such that fNVMOP > 200 KHz can result in incomplete programming or erasure of
the Flash memory array cells.
3.13.1 Mass Erase Timing
The time required to erase the entire NVM array (both program and data) is calculated using the formula:
Eqn. 20
The setup time can be ignored for this operation.
3.13.2 Blank Check Timing
The time it takes to perform a blank check on the program or data Flash is dependant on the location of the
first non-blank word, starting from relative address zero. One fIPS cycle is required per word to be verified,
and the time required for the operation is calculated using the formula:
