5.5 Switching Characteristics Over Recommended Operating Conditions for Clock Domains

PARAMETER CONDITIONS MIN MAX UNIT
fHCLK HCLK - System clock frequency 80 MHz
fGCLK GCLK - CPU clock frequency (ratio fGCLK : fHCLK = 1:1) fHCLK MHz
fVCLK VCLK - Primary peripheral clock frequency 80 MHz
fVCLK2 VCLK2 - Secondary peripheral clock frequency 80 MHz
fVCLKA1 VCLKA1 - Primary asynchronous peripheral clock frequency 80 MHz
fRTICLK RTICLK - clock frequency fVCLK MHz

5.6 Wait States Required

The TCM RAM can support program and data fetches at full CPU speed without any address or data wait states required. There are no registers which need to be programmed for RAM wait states.

The TCM flash can support zero address and data wait states up to a CPU speed of 45 MHz in nonpipelined mode.The flash supports a maximum CPU clock speed of 80 MHz in pipelined mode with no address wait states and one data wait state.

The proper wait states should be set in the register fields Address Setup Wait State Enable (ASWSTEN 0xFFF87000[4]), Random Wait states (RWAIT 0xFFF87000[11:8]), and Emulation Wait states (EWAIT 0xFFF872B8[19:16]) as shown in Figure 5-1.

RM41L232 wait_states_f4_pns186.gifFigure 5-1 Wait States Scheme

The flash wrapper defaults to nonpipelined mode with address wait states disabled, ASWSTEN=0; the main memory random-read data wait state, RWAIT=1; and the emulation memory random-read wait states, EWAIT=1.
