7.1
This LSI has an on-chip 16-Kbyte instruction cache (IC) for instructions and an on-chip 32-Kbyte
operand cache (OC) for data. Half of the memory of the operand cache (16 Kbytes) may
alternatively be used as on-chip RAM. When the EMODE bit in CCR is 0, this LSI's cache
behaves as shown in table 7.1. The features of the cache when the EMODE bit in CCR is 1 are
given in table 7.2. The EMODE bit is initialized to 0 after a power-on reset or manual reset.
This LSI supports two 32-byte store queues (SQs) to perform high-speed writes to external
memory. The features of the store queues are given in table 7.3.
