89 / 92 page  Table 3.2 Access cycles (3 of 3) Peripherals Address Number of access cycles ICLK = FCLK ICLK > FCLK*1 Cycle Unit Related function From To Read Write Read Write FLAD, FACI 0x407F_C000 0x407F_EFFF 3 3 2 to 3 2 to 3 FCLK Data Flash, Flash Application Command Interface Note 1. If the number of PCLK or FCLK cycles is non-integer (for example 1.5), the minimum value is without the decimal point, and the maximum value is rounded up to the decimal point. For example, 1.5 to 2. 5 is 1 to 3. Note 2. When accessing a 16-bit register (FTDRHL, FRDRHL, FCR, FDR, LSR, and CDR), access is 2 cycles more than the value shown in Table 3.2. When accessing an 8-bit register (including FTDRH, FTDRL, FRDRH, and FRDRL), the access cycles are as shown in Table 3.2. Note 3. When accessing the 32-bit register (SPDR), access is 2 cycles more than the value in Table 3.2. When accessing an 8-bit or 16-bit register (SPDR_HA), the access cycles are as shown in Table 3.2. Note 4. The access cycles depend on the QSPI bus cycles. RA4M2 Datasheet Appendix 3. I/O Registers R01DS0367EJ0110 Rev.1.10 Jan 27, 2021 Page 89 of 92 |
