Note 4 In the case of an extended control field, only the first byte is stored in RHCR, the
A frame longer than 32 bytes is transferred to the microcontroller in blocks of 32 bytes plus one
remainder block of length 1 to 32 bytes. The reception of a 32-byte block is reported by a
Receive Pool Full (RPF) interrupt and the data in RFIFO remains valid until this interrupt is
acknowledged (RMC). This process is repeated until the reception of the remainder block is
completed, as reported by RME (figure 51). When the total frame length exceeds 4095 bytes,
bit OV (RBCH) is set but the counter is not blocked. If the second RFIFO pool has been filled
or an end-of-frame is received while a previous RPF or RME interrupt is not yet acknowledged
by RMC, the corresponding interrupt will be generated only when RMC has been issued. When
