BQ76952: during programming, writes appear to succeed, but 2nd check fails

Hello,

I'm programming the chip via I2C and the following struct (a few lines of which are shown here for brevity):

static const uint8_t bq76952_config[] =
{//          cmd  addr  len   data
    (uint8_t)'W', 0x10, 0x03, 0x3E, 0x02, 0x00,
    (uint8_t)'C', 0x10, 0x07, 0x3E, 0x02, 0x00, 0x76, 0x95, 0x00, 0x36,
    (uint8_t)'W', 0x10, 0x03, 0x3E, 0x90, 0x00,
    (uint8_t)'X', 0x05, 0xDC,   // 1500 ms delay
    (uint8_t)'W', 0x10, 0x1E, 0x3E, 0x80, 0x91, 0x57, 0x2F, 0x57, 0x2F, 0x57, 0x2F, 0x57, 0x2F, 0x59, 0x2F, 0x59, 0x2F, 0x59, 0x2F, 0x59, 0x2F, 0x59, 0x2F, 0x59, 0x2F, 0x59, 0x2F, 0x59, 0x2F, 0x5C, 0x2F, 0x5C,
    (uint8_t)'W', 0x10, 0x06, 0x1D, 0x2F, 0x5C, 0x2F, 0x5C, 0x2F,
    (uint8_t)'W', 0x10, 0x03, 0x60, 0x6A, 0x24,
    (uint8_t)'X', 0x00, 0x14,   // 20 ms delay
    (uint8_t)'W', 0x10, 0x03, 0x3E, 0x80, 0x91,
    (uint8_t)'C', 0x10, 0x23, 0x3E, 0x80, 0x91, 0x57, 0x2F, 0x57, 0x2F, 0x57, 0x2F, 0x57, 0x2F, 0x59, 0x2F, 0x59, 0x2F, 0x59, 0x2F, 0x59, 0x2F, 0x59, 0x2F, 0x59, 0x2F, 0x59, 0x2F, 0x59, 0x2F, 0x5C, 0x2F, 0x5C, 0x2F, 0x5C, 0x2F, 0x5C, 0x2F,

The read back of 0x3E is just the subcmd (0x9180) followed by zeros as seen here:

What am I missing?  Longer time delays needed?  Incomplete initialization at top of struct (from BQStudio)?
