Electrical Specifications
6.3.14 MFGPT Signaling
The MFGPT signals detailed in this sub-section use vari-
ous types of buffers depending upon chip configuration. For
a detailed explanation of buffer types, see Table 2-4 "Buffer
Type Characteristics" on page 28.
In this subsection, unless otherwise noted:
• All timing specifications are specified under the oper-
Note 1. GPIO configured: Input Enable and AUX_IN = 1; Output Enable,
Note 2. PIN_OPT_LALL = 0 in Table 2-6 "DIVIL_BALL_OPT" on page 29.
Note 3. t
Note 4. GPIO configured: AUX_IN, Input Enable = 0; Output Enable = 1; Open-drain = 0;
Note 5. GPIO configured: AUX_IN, Input Enable = 0; Output Enable = 1; Open-drain = 0;

Use low-to-high edge if MHZ14_CLK; use high-to-low
edge if KHZ32_XCI. MFGPT7 supports KHZ32_XCI
only.
