Table 5.33 RSPI Timing
Conditions: VCC = AVCC0 = AVCC1 = VCC_USB = V_BATT = 2.7 to 3.6 V, 2.7 ≤ VREFH0 ≤ AVCC0,
VCC_USBA = AVCC_USBA = 3.0 to 3.6 V,
VSS = AVSS0 = AVSS1 = VREFL0 = VSS_USB = VSS1_USBA = VSS2_USBA = PVSS_USBA = AVSS_USBA = 0 V,
PCLKA = 8 to 120 MHz, PCLKB = 8 to 60 MHz, T_a = T_opr
Output load conditions: V_OH = VCC × 0.5, V_OL = VCC × 0.5, C = 30 pF
High-drive output is selected by the driving ability control register.

Note 1. t_PAcyc: PCLKA cycle
Note 2. We recommend using pins that have a letter (“-A”, “-B”, etc.) to indicate group membership appended to their names as groups.
For the RSPI interface, the AC portion of the electrical characteristics is measured for each group.
